Topic: verb (ক্রিয়া),

Best Answer Explained in Below-:

In the given sentence "Anis had Rafique ........... the floor," we need to select an appropriate form of the verb that fits grammatically and contextually. The correct answer is D) "clean."

The phrase "had Rafique clean the floor" employs the structure known as the causative form, where the subject (Anis) causes someone else (Rafique) to perform an action (cleaning). In English, when using this structure, the base form of the verb (clean) follows "had." This is typical in causative constructions, indicating that one person is prompting or directing another to complete a task.

Option A ("would clean") suggests a future or conditional action, which does not fit the context of this sentence. Option B ("to clean") implies intention but lacks the grammatical structure needed here. Lastly, option C ("cleaned") suggests a past action that doesn't align with the causative meaning intended in this context.

Thus, the sentence with "clean" effectively communicates that Anis arranged for Rafique to perform the action of cleaning the floor, making D) "clean" the correct choice.
