The correct answer is A. Date/Time.

A Date/Time data type stores both the date and time. It is the most appropriate data type to store time in MS Access because it allows you to store both the date and time of an event.

A Time Only data type only stores the time. It is not appropriate to store time in MS Access using a Time Only data type because it does not allow you to store the date of an event.

A Time data type is not a valid data type in MS Access.

Date data type stores only the date. It is not appropriate to store time in MS Access using a Date data type because it does not allow you to store the time of an event.
