Task: Answer the multiple choice question.
Question: Which compound has a 18.158\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a S=C(Nc1cccc(Cl)c1)N1CCN(c2ccccn2)CC1
b COc1cccc(CNC(=O)C2CCN(c3nnc(N4CCCC4=O)s3)CC2)c1
c CCc1ccc(C(c2c(C)nn(-c3ccccc3)c2N)c2c(C)nn(-c3ccccc3)c2N)cc1
Answer: b. COc1cccc(CNC(=O)C2CCN(c3nnc(N4CCCC4=O)s3)CC2)c1
