Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 17.277\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(O)CN=CC1=C(O)CC(c2ccccc2)CC1=O
b: CC(=O)c1cccc(NC(=O)c2cc(C)no2)c1
Answer: a. O=C(O)CN=CC1=C(O)CC(c2ccccc2)CC1=O
