Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.840\% 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] COC(=O)C1=C(CSc2nccn2C)NC(=O)NC1c1cc(C)ccc1C
[b] Cc1nccn1CCOc1ccc(Cl)cc1.O=C(O)C(=O)O
Answer: a. COC(=O)C1=C(CSc2nccn2C)NC(=O)NC1c1cc(C)ccc1C
