Task: Answer the multiple-choice question.
Question: Which compound has a 5.536% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=c1ccc2ccc(Oc3ccc([N+](=O)[O-])cc3Cl)cc2o1
b: Cc1ccc(C2(C)NC(=O)N(CC(=O)N3CCN(C(=O)c4cccs4)CC3)C2=O)cc1
c: O=C(N1CCCCC1)C1(S(=O)(=O)c2ccccc2)CC=CC1
Answer: a. O=c1ccc2ccc(Oc3ccc([N+](=O)[O-])cc3Cl)cc2o1
