Task: Answer the multiple-choice question.
Query: Which drug exhibits a -3.752\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1ccc(NC(=O)CS(=O)CC(=O)Nc2cc(Cl)ccc2OC)cc1
b: CSc1ccc(/C=C(/NC(=O)c2ccc(C)cc2)C(=O)Nc2cccc(C)c2)cc1
c: CCN(CC(=O)Nc1ccc(OC)cc1)CC(=O)Nc1ccc(Br)cc1F
d: CCOC(=O)C1(Cc2ccccc2Cl)CCN(S(=O)(=O)N(C)C)CC1
e: Cc1ccc(NC(=O)CS(=O)c2ccccc2N)c(C)c1
Answer: c. CCN(CC(=O)Nc1ccc(OC)cc1)CC(=O)Nc1ccc(Br)cc1F
