Task: Answer the multiple-choice question.
Question: Which drug exhibits a -12.439% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCCCn1c(SCC(N)=O)nc2c(sc3ccccc32)c1=O
(b) O=C(Cn1nc(-c2ccccc2)nc1-c1ccccc1)N1CCOCC1
Answer: a. CCCCn1c(SCC(N)=O)nc2c(sc3ccccc32)c1=O
