Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -22.827\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CN(Cc1ccc(Cl)s1)C(=O)CCl
(b) NC(=O)C1CCN(CC(=O)Nc2cc(Cl)ccc2Oc2ccccc2)CC1
(c) COc1ccc(CN(C)C(c2ccccc2)c2nnnn2-c2ccccc2C)c(OC)c1C
(d) COc1ccc(-n2nc(C(=O)Nc3ccc4c(c3)OCO4)c3c4ccccc4n(C)c3c2=O)cc1
(e) COc1ccc(NC(=O)c2sc(SCc3ccccc3)nc2N)cc1
Answer: a. CN(Cc1ccc(Cl)s1)C(=O)CCl
