Task: Answer the multiple choice question.
Query: Which drug has a -12.147% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCCCCCC(C)n1cc(C(C)=O)c(=O)n(C)c1=O
[b] CN(C)C(=O)c1nc2ccc(Cl)cn2c1CN1CCCC(OCc2cccnc2)C1
Answer: a. CCCCCCC(C)n1cc(C(C)=O)c(=O)n(C)c1=O
