Task: Answer the multiple choice question.
Query: Which compound has a 21.951\% 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: COc1ccc(C(Cl)=C(c2ccc(OC)cc2)c2ccc(OC)cc2)cc1
b: CC(C)n1cnc2cc(NCc3ccccc3O)ccc21
c: CC1CN(S(=O)(=O)c2ccc(NC(=O)c3ccco3)cc2)CC(C)O1
Answer: a. COc1ccc(C(Cl)=C(c2ccc(OC)cc2)c2ccc(OC)cc2)cc1
