Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.938\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) COc1ccc(C)cc1-n1ccn(CC(=O)Nc2ccc(Br)cc2F)c(=O)c1=O
(b) CCOC(=O)C1(CCc2ccccc2)CCN(C2Cc3ccccc3C2)CC1
(c) O=C(C1CCCO1)N1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
Answer: c. O=C(C1CCCO1)N1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
