Task: Answer the multiple choice question.
Query: Which compound exhibits a -42.070% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(NCCN1CCN(C(=O)c2cccc(Br)c2)CC1)C(=O)Nc1ccc(Br)cc1
b Cc1cc(Oc2ccc([N+](=O)[O-])cc2)nc(N2CCOCC2)n1
c CN(C)c1nc(F)c(F)c(S(=O)(=O)c2ccccc2)c1F
Answer: a. O=C(NCCN1CCN(C(=O)c2cccc(Br)c2)CC1)C(=O)Nc1ccc(Br)cc1
