A is silly. Bill 2 is always paid on Thursday (rule 3), so this answer choice adds nothing new.
We’ve seen scenarios where 3 is paid on Thursday too.
B is wrong. Bill 1 never has to go anywhere. It can be paid on Wednesday or Thursday, as long as Bill 5 is paid on the other day.
C is CORRECT. If Bill 4 is paid on Thursday, we’re in the scenario from questions 3-6. Bill 7 has to go with Bill 4, and that forces bills 6 and 3 to be paid on Wednesday.
This scenario proves D and E wrong:

The split in the second hypothetical gets complicated here. Because it seems to me that by using the split both C and D work.

Keep in mind that this is a must be true question. (D) is not necessarily true. If bill 6 is paid on Thursday, bill 3 does not need to be paid on Thursday as well. It could also be paid on Wednesday.
