Step-by-step explanation:
The dayparts that see the largest radio audiences are typically those times when people are most likely to be listening to the radio in their cars or beginning their day. The correct answer is A. Morning drive time and evening drive time. These time slots correspond to when people commute to and from work and are looking for entertainment, news, or traffic updates for their commute.

Shows that aired during these peak times were and still are crucial in reaching a broad audience. Moreover, outlets like National Public Radio (NPR), with its weekly audience of around 27 million listeners, highlight the importance of morning and evening programming as they broadcast lengthy news segments during these dayparts.
