Topic: verb (ক্রিয়া),

Best Answer Explained in Below-:

Intransitive verbs are action verbs that do not require a direct object to complete their meaning. In other words, the action of the verb does not directly affect another noun. In the provided options, let's analyze each sentence:

A) "They painted their fences green." - Here, "painted" is a transitive verb because it takes a direct object, "fences."

B) "My family moved to another city." - In this case, "moved" is the intransitive verb. It does not require a direct object; the sentence conveys a complete thought without needing additional information about what was moved.

C) "We believed the boy." - "Believed" is also transitive as it has a direct object, "the boy."

D) "He gave the papers to the lawyer." - The verb "gave" is transitive because it requires both a direct object ("the papers") and an indirect object ("the lawyer").

Thus, option B stands out as the only sentence featuring an intransitive verb, where the action of moving does not require additional objects, making it the correct answer.
