Problem statement: Answer the multiple-choice question.
Question: Which drug has a 6.373\% 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: CCOC(=O)c1cnc2[nH]c3ccccc3n2c1=O
b: CCCC(=O)Nc1ccc(N2CCN(S(C)(=O)=O)CC2)cc1
c: CC(C)=NNc1cc([N+](=O)[O-])cc2c1C(=O)N(C)S2=O
d: COc1ccccc1CNC(=O)c1cc2sccc2n1C
Answer: c. CC(C)=NNc1cc([N+](=O)[O-])cc2c1C(=O)N(C)S2=O
