Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.913\% 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)(CN2C(=O)COC(=O)CNC(=O)c2ccc(Cl)c(Cl)c2)C1
(b) Cc1cc(C(=O)N2CC(C)CC(C)C2)c(C)o1
(c) CCNS(=O)(=O)c1ccc(NC(=O)Nc2ccccc2OC)cc1
(d) O=C1N[C@@H](Cc2ccccc2)C(=O)N2[C@@H]1C[C@@]1(Br)c3ccccc3N(S(=O)(=O)c3ccccc3)[C@@H]21
Answer: c. CCNS(=O)(=O)c1ccc(NC(=O)Nc2ccccc2OC)cc1
