Topic: verb (ক্রিয়া),

Best Answer Explained in Below-:

The correct answer is A) "Every English sentence must have a verb." This statement highlights a fundamental requirement of English grammar. A verb is essential to form a complete thought and establish the action or state of being in a sentence. For example, sentences like "She runs" or "They are happy" clearly illustrate the necessity of verbs, as they not only convey meaning but also provide structural integrity to the sentence.

Option B, "Every English sentence should have a verb," implies a suggestion rather than a necessity, which makes it less accurate regarding grammatical rules. Option C, "Every English sentence has a verb," inaccurately asserts that every sentence indeed contains a verb, without considering that some phrases may lack one and still be meaningful in certain contexts, such as in fragments. Lastly, option D, "Every sentence has a verb," is overly broad and misleading because it refers to all sentences in general, including those in languages that may not require verbs in the same way English does. Thus, option A is the most precise statement regarding the grammatical structure of English sentences, establishing the verb as a crucial component.
