Task: Answer the multiple choice question.
Query: Which drug has a 14.070\% 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: CCOC(=O)C(CO)(NC(C)=O)C(=O)OCC
b: CCCCn1c(O)c(C(CC)=NCCCn2ccnc2)c(=O)[nH]c1=O
Answer: a. CCOC(=O)C(CO)(NC(C)=O)C(=O)OCC
