Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 2.132\% 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(NC1CCCC1)C(c1ccncc1)N(C(=O)c1ccco1)c1ccccc1
b: O=C(NC1CCCCC1)C(c1ccccc1)N(C(=O)c1csnn1)C1CC1
c: CCCOC(=O)c1c(NC(=O)CCCn2nc([N+](=O)[O-])cc2C)sc(C(=O)OC)c1C
Answer: a. O=C(NC1CCCC1)C(c1ccncc1)N(C(=O)c1ccco1)c1ccccc1
