Task: Answer the MCQ question.
Query: Which drug exhibits a -13.515% 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. CCOP(=O)(OCC)/C(C#N)=C/c1ccc(Br)cc1
b. Cc1ccc(C(=O)N(CN2CCCC2=O)c2ccccc2)cc1C
Answer: a. CCOP(=O)(OCC)/C(C#N)=C/c1ccc(Br)cc1
