d) The boy or the girls come to school late.
Explanation:
Sentence A "The boys or the girls sings in the choir." should be the boys or the girls sing in the choir. The plural subject needs the plural form of the verb, which is sing.
Sentence B " The boys and girl visits my house." should be the boys and the girl visit my house. The boys and the girl are a plural subject, which can be replaced by "they" so, the correct form of the verb is the plural one, visit.
Sentence C "The boys and girl in our club is in the cafe." For this sentence to have a subject-verb agreement, it should say, the boys and girl in our club are in the cafe since the subject is plural, and the verb to be should also be plural, so we change "is" for are.
Sentence D "The boy or the girls come to school late." is the sentence with the subject-verb agreement since the subject (the boy and the girls) is plural, and the verb is in its plural form.too.
