Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 12.657\% 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.) CC(Sc1nnc(C2CC2)n1C1CC1)C(=O)N(C)C1(C#N)CCCCC1
b.) Nc1nc(SCC(=O)Nc2cc(C(F)(F)F)ccc2N2CCOCC2)n[nH]1
c.) CC(NC(=O)Nc1ccc([N+](=O)[O-])cc1)C(c1ccccc1)N1CCOCC1
d.) O=C(Nc1ccc(F)cc1)c1ccccc1NC(=O)C1CC=CCC1C(=O)O
Answer: c. CC(NC(=O)Nc1ccc([N+](=O)[O-])cc1)C(c1ccccc1)N1CCOCC1
