Task: Answer the multiple choice question.
Query: Which drug exhibits a -20.490% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(O)c1ccc(/C=C2\COc3ccccc3C2=O)cc1
[b] COc1ccc2c(c1)c(C(=O)O)c(C)n2C(C)C
Answer: a. O=C(O)c1ccc(/C=C2\COc3ccccc3C2=O)cc1
