Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.729\% 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 other words.
Options:
(a) O=C(CCc1nc2ccccc2[nH]1)N1CCc2ccccc2C1
(b) CCOCC(=O)Nc1nc2ccc(S(C)(=O)=O)cc2s1
(c) O=C(CC1SC(=O)N(c2ccccc2)C1=O)Nc1ccc(Br)cc1
Answer: b. CCOCC(=O)Nc1nc2ccc(S(C)(=O)=O)cc2s1
