Task: Answer the multiple choice question.
Question: Which drug exhibits a 14.645\% 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. CC(=O)c1ccc(NC(=O)c2ccc(-n3cncn3)c([N+](=O)[O-])c2)cc1
b. O=C(c1cn(-c2ccccc2)nc1-c1cccs1)N1CCN(c2ccccc2)CC1
Answer: b. O=C(c1cn(-c2ccccc2)nc1-c1cccs1)N1CCN(c2ccccc2)CC1
