Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -3.774\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) CCOC(=O)C1C(=O)NC(N2CCN(Cc3ccccc3)CC2)=NC1c1ccccc1
b) COc1ccc(C2CC(=O)C(C=NCCN3CCN(C(C)=O)CC3)=C(O)C2)cc1
Answer: a. CCOC(=O)C1C(=O)NC(N2CCN(Cc3ccccc3)CC2)=NC1c1ccccc1
