Task: Answer the multiple choice question.
Query: Which drug exhibits a -5.467% 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(c1ccccc1-c1nc2ccccc2[nH]1)N1CCOCC1
b: CCOC(=O)c1[nH]c2ccc(OC)cc2c1NC(=O)c1ccccc1C(=O)O
Answer: a. O=C(c1ccccc1-c1nc2ccccc2[nH]1)N1CCOCC1
