The subject-verb agreement provides us with the rules of placing a correct verb in correspondence to the subject.
'Mr. Gopalan' is the subject in this sentence. The subject is thus singular.
'Picks' is the singular verb. Thus it is the answer.
'Pick' is the plural verb. Hence, it cannot be placed in this sentence.
