b. he felt forced into making a medicine
Actually questions like these are mentioned to let know YOUR ability of thinking and YOUR language skills. So, it would be better for YOU to answer and think of it by your own. If you don't have ur favs, leave it
C. To advertise a new pair of tennis shoes
The first one is correct. "It is like" the best decision you can ever make.
Saying it that way, is the same as saying that it would be the best decision that you can ever make, but adding more to it. Almost as if soeaking to someone who is overdramatic, and constantly say the word like.
I hope this helps
