Task: Answer the multiple choice question.
Query: Which compound exhibits a -0.940\% 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, or c without using any additional words.
Options:
(a) COc1nnc(-c2ccc(C)c(S(=O)(=O)NCCO)c2)c2ccccc12
(b) Cc1ccccc1NCC(=O)N=Nc1c(O)[nH]c2ccc([N+](=O)[O-])cc12
(c) CCOC(=O)C1=C(CCc2ccccc2)NC(=O)NC1c1cccc([N+](=O)[O-])c1
Answer: a. COc1nnc(-c2ccc(C)c(S(=O)(=O)NCCO)c2)c2ccccc12
