Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.195\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1cccc(OC)c1C(=O)OCC(=O)Nc1cccnc1Cl
b: O=C(CN1C(=O)NC2(CCCC2)C1=O)Oc1ccc2ccc(=O)oc2c1
Answer: b. O=C(CN1C(=O)NC2(CCCC2)C1=O)Oc1ccc2ccc(=O)oc2c1
