Answer:
lower right.
Step-by-step explanation:
The top left is sort of absurd. It says that she uses more ribbon than she has.
The top right is equally wrong or at least the answer as given. Both 3/8 s mentioned are the same thing and both don't describe the process of multiplication.
The lower left is not correct. You would be taking 1/2 of 3/8, not 1/2 of 3/4.
That only leaves you with the lower right which takes 1/2 of 3/4 and that is correct.
