I'm studying this problem for my genetics final: enter image description here

My Attempt: The answer for part B is met2 and the answer for part C is Df1. Met2 and met 1 both have 1 no so i'm not sure how met2 is in the middle. I didn't even know complementation tests could tell gene location. I think the answer to part C is because df1 has the most NOs, which means it's missing the most DNA. (If it had that DNA, it would complement).
