Task: Answer the multiple choice question.
Question: Which compound exhibits a -8.003\% 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] O=C1CSC(c2ccccc2)N1c1nc(-c2ccc(Cl)cc2Cl)cs1
[b] COC(=O)c1ccc(C(C(=O)NCc2ccccc2)N(Cc2cccs2)C(=O)c2cnccn2)cc1
[c] CC(=O)Nc1ccc(NC(=O)c2cccc3ccccc23)cc1
Answer: b. COC(=O)c1ccc(C(C(=O)NCc2ccccc2)N(Cc2cccs2)C(=O)c2cnccn2)cc1
