Task: Answer the multiple-choice question.
Query: Which drug has a -21.175\% 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 additional words.
Options:
a: Cc1cc(C)nc(NC(=O)c2cccc([N+](=O)[O-])c2C)n1
b: CCOC(=O)C1(CC2CC2)CCN(Cc2cn[nH]c2-c2cccc(F)c2)CC1
c: O=C(Nc1ccc(NC(=O)c2ccco2)nc1)c1cccc(F)c1
d: CN(C)c1ccc(/C=N/NC(=O)CNC(=O)/C=C/c2ccccc2)cc1
Answer: a. Cc1cc(C)nc(NC(=O)c2cccc([N+](=O)[O-])c2C)n1
