The correct answer is C. picks.
The verb “pick” is used to describe the action of taking something up or off the ground. In this case, Mr. Goplan is taking his daughter up from school. The action is repeated every day at 4:30, so the present tense form of the verb is used.
The other options are incorrect because they do not agree with the tense of the sentence. The verb “picked” is in the past tense, but the action is happening every day. The verb “pick” is in the infinitive form, but it is not followed by a direct object. The verb “none of the above” is not a verb, so it cannot be the correct answer.
