In the following sentence improvement question, choose the alternative that best improves the underlined phrase so that the sentence becomes grammatically correct and natural: "You have come here with the intention in insulting me."

Introduction / Context:
This sentence improvement question checks your understanding of correct prepositional usage with the phrase "intention of doing something." Exams in English grammar often test fixed expressions and collocations where only one preposition is idiomatic and accepted in standard English.

Given Data / Assumptions:

• Original sentence: "You have come here with the intention in insulting me."
• The underlined phrase is "with the intention in insulting me."
• You must choose the option that makes the sentence grammatically correct and natural.
• The intended meaning is that the person came with a plan or purpose to insult the speaker.

Concept / Approach:
In English, we use the fixed collocation "with the intention of doing something." The noun "intention" is normally followed by the preposition "of" when we add a verb in the ing form. Phrases such as "the intention of helping," "the intention of cheating," or "the intention of resigning" are standard. Using "in" or "on" with "intention" before a gerund is not idiomatic and sounds incorrect to native speakers.

Step-by-Step Solution:
Step 1: Identify the key noun and verb pattern: "intention + preposition + insulting." Step 2: Recall the standard collocation "intention of doing something." Step 3: Replace "in insulting me" with "of insulting me." Step 4: Check the entire sentence: "You have come here with the intention of insulting me." Step 5: Confirm that the sentence is now grammatically correct and sounds natural.

Verification / Alternative check:
You can compare with similar sentences. For example, "He spoke with the intention of helping" or "She called with the intention of complaining." In each case, the pattern "intention of" is used. If we try "intention in helping" or "intention on complaining," they sound wrong. This confirms that only "of insulting me" fits correctly in the given question.

Why Other Options Are Wrong:

• for insulting me: The phrase "with the intention for insulting me" is not idiomatic English. We use "intention of," not "intention for," before a gerund.
• on insulting me: "Intention on" is also non standard. We may say "bent on insulting," but not "intention on insulting."
• No improvement: The original phrase with "in insulting me" is grammatically incorrect and unidiomatic, so no improvement cannot be chosen.

Common Pitfalls:
Many learners translate directly from their first language and choose prepositions by guesswork, leading to phrases like "intention to," "intention for," or "intention in" with gerunds. Remember that prepositions in English are often fixed by usage. Learning typical patterns such as "intention of doing," "aim of doing," and "purpose of doing" will greatly improve accuracy in sentence improvement questions.

Final Answer:
The correct improvement is of insulting me, giving the sentence: You have come here with the intention of insulting me.
