Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.735% 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 additional words.
Options:
a O=S(=O)(Nc1nc2ccccc2s1)c1ccc(Cl)nc1
b Cc1ccc(C2C(S(C)(=O)=O)=C(O)C(=O)N2c2ccccc2)cc1.Nc1ccccc1
Answer: a. O=S(=O)(Nc1nc2ccccc2s1)c1ccc(Cl)nc1
