Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.343% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CN(C)c1cnn(-c2ccccc2)c(=O)c1Cl
b: O=C(NC1CCCCC1)c1ccc(COc2ccccc2)o1
Answer: a. CN(C)c1cnn(-c2ccccc2)c(=O)c1Cl
