Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.349\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. Cc1cc(C)c(NC(N)=S)c(C)c1
b. O=S(=O)(Nc1nc2ccccc2nc1Cl)c1ccc(Cl)cc1
Answer: a. Cc1cc(C)c(NC(N)=S)c(C)c1
