Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 10.621\% 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(=O)c1nc(N2C(=O)CC(Cc3ccccc3)C2=O)sc1C
b: O=C1C2ON(c3ccccc3)C(c3cccnc3)C2C(=O)N1c1ccccc1
Answer: b. O=C1C2ON(c3ccccc3)C(c3cccnc3)C2C(=O)N1c1ccccc1
