Directions: The following items have four sentences, one of which is correct. Select the correct sentence.

Step-by-step solution

The sentence requires a subject for the verb 'has'. The subjective case is 'who', whereas 'whom' is the objective case. This eliminates the options with 'whom'. Between 'among' and 'amid', 'among' is the correct preposition to use when referring to a group of countable people or things, such as 'you'. 'Amid' is typically used for uncountable nouns or to mean 'surrounded by' in a physical or abstract sense. Therefore, 'Who among you has the answer?' is the grammatically correct sentence.
