Task: Answer the multiple choice question.
Query: Which drug exhibits a 26.663\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCOC(=O)c1sc(N)nc1-c1ccccc1
(b) Cc1cc(C)c(C(=O)CSc2nnc(C)s2)c(C)c1
(c) N#Cc1c(-c2ccccc2)nc(-c2ccccc2)[nH]c1=O
(d) CCCC(=O)Nc1ccc(NC(=S)NC(=O)c2ccccc2[N+](=O)[O-])cc1
Answer: b. Cc1cc(C)c(C(=O)CSc2nnc(C)s2)c(C)c1
