Task: Answer the multiple choice question.
Question: Which compound has a -28.233\% 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: CC1(C)CC2CC(C)(CN2CC(O)c2ccccc2)C1.O=C(O)C(=O)O
b: CCN(CC)CCN1C(=O)C(O)=C(C(=O)c2ccco2)C1c1ccccn1
c: Cc1cc(C)n2nc(CNS(=O)(=O)c3ccc([N+](=O)[O-])cc3)nc2n1
d: O=C(Nc1ccc(N2CCOCC2)c(S(=O)(=O)Nc2ccccc2Cl)c1)c1ccccc1
Answer: a. CC1(C)CC2CC(C)(CN2CC(O)c2ccccc2)C1.O=C(O)C(=O)O
