Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.407\% 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 or b without using any other words.
Options:
a: CCOc1cc(/C=C2\NC(=S)N(c3c(C)n(C)n(-c4ccccc4)c3=O)C2=O)ccc1O
b: CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1cccc(Cl)c1Cl
Answer: b. CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1cccc(Cl)c1Cl
