Task: Answer the multiple choice question.
Query: Which drug exhibits a 14.358\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) Cn1c(=O)c2c(n(C)c1=O)=NC1(CCCCC1)N=2
(b) CCCCCN(C(=O)NC(=O)NC(C)CC)S(C)(=O)=O
(c) COc1cccc(NC(=O)CSc2nnc3c(n2)[nH]c2ccc(C)cc23)c1
Answer: b. CCCCCN(C(=O)NC(=O)NC(C)CC)S(C)(=O)=O
