২৮. We should respect our teacher. (Imperative)

The correct answer is (b) Let us respect our teacher. Sentence Transformation Analysis: The original sentence is Assertive. To convert it into an Imperative sentence, the structure changes as follows: When the subject is "we" and the sentence expresses a suggestion, advice, or request, the Imperative form uses "Let us + Base Verb". Formula: We should + V1 → Let us + V1 We should respect → Let us respect our teacher. ✗ Option (a): "Respect our teacher" — this is 2nd person imperative (You), not "we". ✗ Option (c): Changes the meaning entirely (negative). ✗ Option (d): Passive voice transformation, not imperative.
