Which sentence has correct subject-verb agreement?

The first sentence accurately demonstrates correct subject-verb agreement. In this context, the subject "each" is a singular pronoun, which means it requires a singular verb. The sentence correctly uses "asks," which agrees with the singular nature of "each of the children."

This construction emphasizes individual actions rather than grouping all children together. As a result, the sentence maintains both clarity and grammatical accuracy. The other options contain subjects that require plural forms of the verb, which leads to incorrect agreement.
