Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.137\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CCOC(=O)/C=C/c1nc(C(=O)OCC)c(C)c(=O)[nH]1
b.) O=C(CSc1ccc(-c2ccco2)nn1)NCCc1ccccc1
Answer: a. CCOC(=O)/C=C/c1nc(C(=O)OCC)c(C)c(=O)[nH]1
