Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.696\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CN(C(=O)c1cccnc1)c1nnc(-c2cnccn2)s1
b) CCOC(=O)N1CCN(C(=O)Nc2cccc(Cl)c2)CC1
c) COc1ccc(C(=O)Cn2c(Br)nc3c2c(=O)n(C)c(=O)n3C)cc1OC
Answer: c. COc1ccc(C(=O)Cn2c(Br)nc3c2c(=O)n(C)c(=O)n3C)cc1OC
