Task: Answer the multiple choice question.
Query: Which drug exhibits a -17.274% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) Cn1c(SCc2ccccc2)nc(N)c(N=O)c1=O
b) Cc1cccc(NC(=O)Cn2nnc(-c3ccc(CN4CCCC4)cc3)n2)c1C
c) Cc1ccccc1/[N+]([O-])=C/c1cccs1
Answer: a. Cn1c(SCc2ccccc2)nc(N)c(N=O)c1=O
