@Kristen Lee I also thought this - it seemed the author was neutral so I chose C.

Q4 (PT106.S1.Q24) was straightforward, I was really surprised it was a 5/5 difficulty question afterwards. Got A correct in 1:03 (6 seconds under). It was intuitive to link "symbolize" in last sentence to answer A - something mentioned in review for SA section. 5/5 correct on this drill set - big confidence boost after a very hard module.
