Task: Answer the multiple choice question.
Query: Which compound exhibits a 11.052\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=c1ccc(-c2ccccc2)nn1Cc1ccccc1
b O=C(Nn1cnnc1)C(c1ccccc1)c1ccccc1
Answer: a. O=c1ccc(-c2ccccc2)nn1Cc1ccccc1
