In the sentence “Your admission into this university will be dependent on the marks you score in the entrance examination”, which of the following options best corrects the underlined words so that the sentence becomes grammatically and idiomatically accurate?

Introduction / Context:
This question assesses your understanding of correct verb forms and idiomatic usage in English grammar. In particular, it focuses on how to express future dependence or condition using the appropriate auxiliary and base verb combination. Such questions commonly appear in banking, management and other competitive exams to test whether candidates can identify subtle errors in tense and structure that affect clarity and correctness in formal writing.

Given Data / Assumptions:
1) The original sentence is: Your admission into this university will be dependent on the marks you score in the entrance examination.2) The phrase to be corrected is “will be dependent on”.3) The time reference is clearly future, because it refers to admission that will happen based on marks scored.4) Options provide alternative verb forms: is depending, will depend, depending and depends.

Concept / Approach:
Standard English prefers active constructions like “will depend on” instead of unnecessarily heavy passive style “will be dependent on” when the subject is non human or abstract. For expressing a future conditional relationship, the usual pattern is subject plus will plus base verb. Here, “admission” is a singular noun, but when combined with the modal auxiliary will, the main verb always takes its bare infinitive form depend. You should therefore search for the option that correctly expresses future dependence with will plus depend.

Step-by-Step Solution:
1) Identify the tense and meaning: The sentence refers to a future event where admission depends on entrance examination marks.2) Recognise that “will be dependent on” is grammatically possible but unnecessarily wordy and less natural in exam style English, where concise active forms are preferred.3) The desired structure is subject plus will plus base verb, that is “admission will depend on the marks”.4) Check each option: “is depending” uses present progressive, which does not match the future conditional sense.5) “will depend” exactly matches the pattern will plus base verb and expresses the intended meaning clearly.6) “depending” alone is a participle and cannot serve as the main verb in this clause without an auxiliary.7) “depends” is simple present and would be correct only if we were making a general statement without explicit future reference; the sentence specifically uses will, so “will depend” is better aligned.

Verification / Alternative check:
Read the corrected sentence with each option to test for naturalness and correctness. With “will depend”, the revised sentence becomes: Your admission into this university will depend on the marks you score in the entrance examination. This version is smooth, concise and grammatically clean. When you try “is depending”, the sentence sounds awkward and suggests the dependence is happening right now, which is illogical. “Depending” on its own makes the clause incomplete, and “depends” clashes with the explicit future sense implied by “will”. Therefore, “will depend” stands out as the only fully appropriate correction.

Why Other Options Are Wrong:
“is depending” uses present continuous and does not correctly express a future condition.“depending” alone cannot function as the main verb of the clause and leaves the sentence grammatically incomplete.“depends” could be used in a general rule like “admission depends on marks,” but in the given future oriented sentence the modal will requires the base verb depend, not depends.None of these is incorrect because one of the options, will depend, already provides the standard grammatical form.

Common Pitfalls:
Many learners are tempted to use be plus dependent because it looks similar to constructions they have seen in formal writing. However, exam setters often prefer more direct wording. Another frequent mistake is ignoring the presence of a modal auxiliary like will when choosing the main verb form. Remember that after will, would, can, could, may, might and similar modals, the main verb should always appear in its base form. Keeping this rule in mind makes such correction questions much easier to handle.

Final Answer:
The grammatically and idiomatically correct correction is will depend.
