Best way to solve these types of questions is by noting which bold faced part is a fact and which one is an opinion.
The first is evidence strengthening an unrepeated experimental result; the second is a claim supported by that evidence.
Only C says that first one is a fact/evidence. Second is obviously a claim.
C is right!
