Task: Answer the multiple choice question.
Question: Which drug exhibits a -12.523% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccc([C@@H]2[C@@H]3C(=O)N(C(C)(C)C)C(=O)[C@@H]3[C@]3(Cc4ccc(Cl)cc4)C(=O)N(c4ccc(Br)cc4)C(=O)N23)cc1
b: CC(C)COc1cccc(C(=O)Nc2ccc(N3CCOCC3)cc2N2CCOCC2)c1
c: CCN1CCN(c2nc3ccccc3s2)CC1
d: COc1ccc(OCC(=O)NS(=O)(=O)c2ccc(Cl)cc2)cc1
Answer: c. CCN1CCN(c2nc3ccccc3s2)CC1
