That's what I did too. Process of elimination. I crossed out the two that I was so sure wasn't the answer and focused on the other two. Like the tibialis anterior. I know that it doesn't belong to the arm or hand or thigh (femur) so it's between the foot or lower leg. Also know dorsiflexon and abduction and addiction. It's not as hard as it seems. It's truly just testing your ability to see how you can test.
