Task: Answer the multiple-choice question.
Query: Which drug exhibits a -16.521\% 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: CN1CCN(C(=S)NC(=O)/C=C/c2ccccc2)CC1
b: COc1ccc(C(C(=O)NC2CCCCC2)N(Cc2cccs2)C(=O)Cc2c[nH]c3ccccc23)cc1OC
Answer: a. CN1CCN(C(=S)NC(=O)/C=C/c2ccccc2)CC1
