Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.102\% 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: COc1ccc(C(=O)NC(=S)NCc2ccccc2)cc1OC
b: O=C(NC1CCCCC1)C(c1cccs1)N(C(=O)c1ccccn1)c1ccccc1
Answer: a. COc1ccc(C(=O)NC(=S)NCc2ccccc2)cc1OC
