What does it mean when two objects are said to exert a mutual force of attraction? A. Each takes turns attracting the other. B. They attract each other at the same time.
C. A third object takes turns attracting each of them.
D. A third object attracts them both at the same time.

B

It says "mutual", so both objects are attracting at the same time. In addition, I do not believe it is possible for objects to take turn acttracting each other so I believe A is false. I think C and D are wrong because a third object is not related to any of these choices. It also explicitly states "two objects" and when it says mutual, it means they are attracting each other.
