Task: Answer the multiple choice question.
Question: Which compound has a 13.642\% 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) CCC(CC)C(=O)Nc1ccc([N+](=O)[O-])cn1
b) O=C(O)C1(c2ccccc2)CCN(S(=O)(=O)c2ccc(F)c(F)c2)CC1
c) O=C(NCCN1CCCCC1)Nc1ccc(F)c(Cl)c1
d) O=c1c2cc(F)ccc2sn1-c1ccc(F)cc1
Answer: c. O=C(NCCN1CCCCC1)Nc1ccc(F)c(Cl)c1
