Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.672\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) COc1ccc(C(=O)CN2C(=O)NC(C)(c3ccc(C)cc3)C2=O)cc1OC
(b) Cc1c(C)c2ccc(OCC(=O)N3CCC(C(=O)O)CC3)cc2oc1=O
Answer: a. COc1ccc(C(=O)CN2C(=O)NC(C)(c3ccc(C)cc3)C2=O)cc1OC
