Task: Answer the MCQ question.
Query: Which drug exhibits a 8.412\% 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) CN(CCO)C(=O)CCC(=O)Nc1ccc(S(N)(=O)=O)cc1
(b) O=C(CNc1cccc(S(=O)(=O)N2CCOCC2)c1)Nc1cccc(Br)c1
(c) CCc1nc(-c2ccccc2)cc(=O)[nH]1
