Answer:
B. Complete all assigned reading, so you will be familiar with the
content being discussed.
Explanation:
The lecture is not a test, and the only thing required is to complete all assigned ready so you are familiar with the content being discussed. This is what is important, and hence you should not swap notes with classmates who attended the last lecture or bring a recording device since you need to learn by yourself, and hence you should take notes, and be up with all assigned readings. Hence, B is the correct option.
