Task: Answer the multiple choice question.
Query: Which drug exhibits a -6.359\% 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: CC(C)(C)CNC(=O)c1ccc2c(c1)S(=O)(=O)c1cc(Cl)ccc1C2=O
b: CCNS(=O)(=O)c1ccc(NC(=O)Cn2cc([N+](=O)[O-])cn2)cc1
c: Cc1nc2c(sc3nc4c(cc32)COC(C)(C)C4)c(=O)o1
d: CN(C)/C=C(\C#N)C(=O)Nc1ccc(F)c(Cl)c1
Answer: c. Cc1nc2c(sc3nc4c(cc32)COC(C)(C)C4)c(=O)o1
