In this error-spotting question, identify which part of the sentence has an error in standard English usage: "I will not (A) / stay here another minute (B) / if I can help it! (C) / No Error (D)".

Introduction / Context:
Error-spotting questions present a complete sentence divided into labelled parts and ask you to decide which part, if any, contains a grammatical or usage error. In this sentence, "I will not (A) / stay here another minute (B) / if I can help it! (C) / No Error (D)", you must judge whether any of the three textual parts A, B or C contain a mistake, or whether the sentence is fully correct, in which case you choose D.

Given Data / Assumptions:

• Part A: "I will not".
• Part B: "stay here another minute".
• Part C: "if I can help it!".
• Option D represents "No Error".
• The full sentence expresses strong refusal to remain somewhere any longer, provided the speaker has the ability to leave.

Concept / Approach:
The idiom "if I can help it" means "if I can possibly prevent it." The entire sentence "I will not stay here another minute if I can help it" is a perfectly natural and correct way of saying "I absolutely do not want to stay and will leave as soon as possible if it is within my control." Each part obeys standard grammar: the future negative "will not," the phrase "stay here another minute," and the conditional clause "if I can help it." Because there is no grammatical, structural or idiomatic error, the correct choice is "No Error."

Step-by-Step Solution:
Step 1: Analyse part A "I will not." This is a correct future tense negative form and needs no change.Step 2: Analyse part B "stay here another minute." The verb "stay" correctly follows "will not," and "another minute" is a natural expression of a small amount of time. There is no mistake.Step 3: Analyse part C "if I can help it!" This is a standard idiom meaning "if it is possible for me to avoid it," and the grammar is correct.Step 4: Combine the three parts into the full sentence to check overall sense: "I will not stay here another minute if I can help it!"Step 5: Confirm that the sentence is idiomatic, coherent and grammatically sound.Step 6: Since none of A, B or C contains an error, select part D "No Error" as the answer.

Verification / Alternative Check:
To verify, compare with similar sentences in everyday English such as "I will not talk to him again if I can help it" or "I am not going to miss this chance if I can help it." The structure and idiom are the same. If we tried altering any part, for example changing "another minute" to "other minute" or "if I can help it" to "if I could help it," the sentence would become incorrect or change meaning. Because the original sentence matches standard patterns, it must be treated as error free.

Why Other Options Are Wrong:
If you choose A, B or C, you must point to a specific grammatical rule being violated, but none of these parts actually breaks any rule. Part A uses correct future tense; part B has proper verb-object structure and time phrase; part C uses a well-established idiom with the correct modal "can." Therefore, marking any of A, B or C as erroneous would be unjustified. The whole sentence reads smoothly and naturally, so "No Error" is the only defensible choice.

Common Pitfalls:
Many candidates assume that there must always be an error somewhere and avoid choosing "No Error." Others may be unfamiliar with the idiom "if I can help it" and suspect that the modal verb is wrong. In competitive exams, however, some sentences are deliberately correct to test whether you can resist the urge to over-correct. The best strategy is to check each part carefully and, if you find nothing wrong, confidently select the "No Error" option.

Final Answer:
The sentence is grammatically correct, so the correct choice is D (No Error).
