Task: Answer the multiple-choice question.
Question: Which drug has a 11.878\% 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, d, or e without using any other words.
Options:
(a) COc1ccc(-c2cc(C#N)nc(N3CCN(C)CC3)n2)cc1
(b) COc1ccc(/C(C)=N/NC(=O)CNC(=O)COc2ccccc2)c(OC)c1
(c) O=C(CSc1n[nH]c(-c2cccnc2)n1)Nc1ccccc1[N+](=O)[O-]
(d) CCOc1ccc(NC(=O)c2nn(C)c(C(=O)Nc3ccc(OCC)cc3)c2[N+](=O)[O-])cc1
(e) CCCCN(CCCC)C(=S)NC(=O)C(C)(C)C
Answer: c. O=C(CSc1n[nH]c(-c2cccnc2)n1)Nc1ccccc1[N+](=O)[O-]
