The question and all of the choices are rather messy and misleading.

Here's a simple statement that you can use to make the best match:

If the two forces are equal, then more work is done by the force that
continues to be applied through the greater distance.

Answer:

C

Explanation:

THIS IS TRUE BECAUSE I TOOK THE TEST, and because THE EQUATION FOR WORK IS WORK = FORCE * DISTANCE AND EVEN THO THEY BOTH HAVE THE SAME FORCE THE OTHER ONE HAS MORE DISTANCE, ITS LIKE SAYING WHICH EQUAION HAS A BIGGER ANSWER 1*1 OR 1*2 WELL ITS OBVIOUSLY THE SECOUND EQUATION SO THE ANSWER IS C LIKE I SAID BEFORE

BTW  AL2006 IS WRONG AND I DONT EVEN UNDERSTAND WHAT HE EVEN THO HE IS "TRUSTED"
