Task: Answer the multiple-choice question.
Query: Which drug has a -5.386% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCOC(=O)CSc1nc(C)c(C(C)=O)cc1C#N
(b) CC1CCC2C(=O)N(c3ccc(C(=O)NCc4ccccc4)cc3)C(=O)C2C1
Answer: a. CCOC(=O)CSc1nc(C)c(C(C)=O)cc1C#N
