Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.710\% 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 additional words.
Options:
[a] CCOC(=O)C1(c2ccccc2)NC(c2ccccc2C)C2C(=O)N(c3ccc4c(c3)OCO4)C(=O)C21
[b] Cc1cccc2cc(CN(Cc3cccnc3)C(=O)c3ccncc3)c(=O)[nH]c12
[c] COc1ccccc1Nc1cc(N2CCOCC2)c2nonc2c1[N+](=O)[O-]
[d] COc1ccc(Cc2nnnn2CC(=O)O)cc1
[e] S=c1[nH]nc(NCCc2ccccc2)s1
Answer: c. COc1ccccc1Nc1cc(N2CCOCC2)c2nonc2c1[N+](=O)[O-]
