Problem statement: Answer the multiple-choice question.
Query: Which compound has a 15.784\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(O)C(C(=O)O)=C1C2CC3CC(C2)CC1C3
b O=C(c1cc(Cl)nc2ccccc12)N(Cc1nnc(-c2ccccc2Cl)o1)C1CC1
Answer: a. O=C(O)C(C(=O)O)=C1C2CC3CC(C2)CC1C3
