Task: Answer the multiple choice question.
Query: Which drug exhibits a 11.033\% 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: O=C1C(=C(c2ccccc2)c2ccccc2)Nc2ccccc21
b: COc1cccc(NC(=O)c2ccc3c(c2)N(CC(=O)N2CCCCC2)C(=O)C(C)(C)O3)c1
Answer: a. O=C1C(=C(c2ccccc2)c2ccccc2)Nc2ccccc21
