Answer 2

Answer:

C or the third one.

Explanation:

"As we approached the end of the year, we made sure to begin practicing well in advance of the final exam."

The only difference between B and C is the comma after year, think of a comma as a pause. If you pause where the comma is does the sentence still make sense?  

Hope this helps!
