Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.636\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CC(C)CC1(C)N=C(c2ccccc2)C(=S)N1
b: CN(C)c1ccc(/C=[N+](\[O-])C2SC(=S)N(C)C2(C)C)cc1
Answer: a. CC(C)CC1(C)N=C(c2ccccc2)C(=S)N1
