Task: Answer the multiple choice question.
Question: Which compound exhibits a -2.601% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCN(CC)CCCNc1cc(C)nc2cc(-c3cccs3)nn12
b COc1cc(C(=O)OCCn2c(=O)c3c(ncn3CCN(C)C)n(C)c2=O)cc(OC)c1OC.Cl
c CC(C)(C)c1ccc(C(=O)NN=C2CCCC2)cc1
d CC(C)[C@H](NC(=O)[C@@H]1Cc2ccccc2CN1)C(=O)Nc1ccc2c(c1)OCCO2
e CSc1c(CC(=O)Nc2ccccc2)n(C)c2ccccc12
Answer: b. COc1cc(C(=O)OCCn2c(=O)c3c(ncn3CCN(C)C)n(C)c2=O)cc(OC)c1OC.Cl
