Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.113% 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, or d without using any other words.
Options:
a: Cc1ccc(C)c(C(=O)NCCN(C)C)c1
b: COc1cc(C=O)ccc1OCc1cccc(Br)c1
c: CN1CCN(C(=O)c2ccccc2N(Cc2ccccc2)S(=O)(=O)c2ccccc2)CC1
d: COc1cc(Nc2ccc(-c3ccccc3F)nn2)cc(OC)c1OC.Cl
Answer: b. COc1cc(C=O)ccc1OCc1cccc(Br)c1
