If Lin appears immediately before Geyer, then which one of the following must be true?

Why can't A or B serve as correct answers?

If LG is a block, why can't G appear no later than third? Also, why can't H appear last? I eliminated answer choices D and E, but I couldn't figure out why A, B, and C weren't all correct answers - apart from the fact that there's only one correct answer.

Hi, this is asking us what must be true, not what could be true. Wrong answers could still happen, but they do not have to happen. C however must be true. Since L must be before H, J, and G, L cannot go later than third.
