Task: Answer the multiple-choice question.
Query: Which compound exhibits a 16.968% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a C/C(Nc1ccc(Cl)cc1)=C(/C#N)C(N)=O
b CCOC(=O)/C=C/C(=O)Nc1ccc(S(=O)(=O)N2CCCCCC2)cc1
Answer: a. C/C(Nc1ccc(Cl)cc1)=C(/C#N)C(N)=O
