Task: Answer the multiple-choice question.
Question: Which drug exhibits a -10.575% 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, or c without using any additional words.
Options:
a: O=C(NCc1ccccc1Cl)c1cccc(OC2CCN(C(=O)C3CC3)CC2)c1
b: COc1cccc(C(=O)c2c(C)c(CCC#N)n3ccccc23)c1
c: CN(CC(=O)NC(=O)NCc1ccco1)Cc1nc2ccccc2c(=O)[nH]1
Answer: b. COc1cccc(C(=O)c2c(C)c(CCC#N)n3ccccc23)c1
