Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.253\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CN(C)c1nc(N)c([N+](=O)[O-])c(NCC2CCCO2)n1
(b) CCOC(=O)C(=CNc1ccc(-c2ccco2)c(Cl)c1)C(=O)OCC
(c) CCOC(=O)C1=C(COc2ccccc2)NC(=O)NC1c1ccc(Br)cc1
(d) CC(C)(C)C(=O)N1CCN(c2ccc(NC(=O)c3ccc([N+](=O)[O-])o3)cc2)CC1
Answer: a. CN(C)c1nc(N)c([N+](=O)[O-])c(NCC2CCCO2)n1
