Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.968\% 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) O=C(Nc1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1)N1CCN(c2ccccn2)CC1
(b) COC(=O)c1c(NC(=O)c2ccnn2C)sc(C)c1C
(c) O=c1cc(Cc2nnc(SCc3ccccc3)n2-c2ccc(Cl)cc2)[nH]c(=O)[nH]1
Answer: a. O=C(Nc1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1)N1CCN(c2ccccn2)CC1
