B

Explanation

According to the “ S ubject-Verb Agreement Rule” , a singular subject always takes a singular verb and a plural subject always takes a plural verb. Similarly in this question, ‘Everybody’ is used for a single person and considered to be a singular subject which will take singular verbs. Hence, ‘knows’ and ‘agrees’ will be the most appropriate answer
