Answer:
The correct answer is letter "A": A podcast.
Explanation:
Podcasts are recordings in which speakers talk about certain topics in the form of an interview providing explanations, details, and information that could be of interest to the target audience. Podcasts do not require the interaction between the speaker and the audience and can be accessed by individuals from different devices as long as the speaker and the audience share the same platform.
