Problem statement: Answer the multiple-choice question.
Query: Which drug has a -21.450\% 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 other words.
Options:
a O=C(NNC(=O)c1nn(-c2ccc(F)cc2)ccc1=O)c1ccc(Cl)cc1
b CCOCC(=O)Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1
c Cc1ccc2[nH]c(=O)c(CN(C(=O)c3cccc([N+](=O)[O-])c3)C(C)C)cc2c1
d NC(=O)CC(NC(=O)Cc1ccc(Br)cc1)c1ccc(NCCOc2ccccc2)c([N+](=O)[O-])c1
Answer: c. Cc1ccc2[nH]c(=O)c(CN(C(=O)c3cccc([N+](=O)[O-])c3)C(C)C)cc2c1
