Explanation:

- The initial sentence has a grammatical issue with subject-verb agreement. "Smell" is singular, so the verb should also be in singular form.

- Option 2: makes me feel

- This option corrects the subject-verb agreement error. "Makes" is the correct singular form for the verb to agree with "smell." The phrase "me feel" correctly follows the verb.

- Option 1: making I feel

- This option is grammatically incorrect. "I" should be "me," and "making" is not the correct verb form.

- Option 3: make me feeling

- This option is incorrect because "make" does not agree with "smell." Also, "feeling" is not the right form.

- Option 4: No improvement required

- This is incorrect because the original sentence has subject-verb agreement issues.
