The subject "nobody" is a singular indefinite pronoun. In subject - verb agreement, singular indefinite pronouns take singular verbs. The verb "laugh" is in the base form (used for plural subjects or first/second person singular in present simple). The correct singular form of the verb for the third - person singular subject "nobody" in the present simple tense is "laughs".

Answer:

Incorrect verb: laugh
Correct verb: laughs
