Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. do.
Context:
The sentence is in the simple present tense and expresses a general truth or advice.
Hence, the verb should also be in the base form — “do.”
Meaning of the words:
-
Done: past participle form; used with “have” (e.g., have done).
-
Do: base form of the verb; used for general statements.
-
Did: past tense form; used for actions already completed.
-
Does: used with singular subjects (he/she/it).
Correct word:
Do — because the subject “we” is plural and the sentence expresses a general rule or habit.
Reason:
The phrase “do our best” means to make the greatest possible effort.
Final Sentence:
We should always do our best to help others.
Hence, the chosen option will be correct.
