Children generally ______ with others of the same size and age.
Correct Answer: A
Rationale: The correct answer is 'Play' because 'Children' is a plural subject and requires the base form of the verb. When referring to a plural subject like 'Children,' the verb should be in its base form without an added 's' or 'ed.' In this context, 'Play' is the appropriate form to use to match the subject 'Children.'
Choice B, 'Plays,' is incorrect because it is the singular form of the verb and does not agree with the plural subject 'Children.' Choice C, 'Played,' is incorrect as it is the past tense form of the verb and does not fit the present tense context of the sentence. Choice D, 'Playing,' is incorrect as it is the present participle form of the verb and does not match the simple present tense needed in the sentence.
