Task: Answer the multiple-choice question.
Query: Which drug exhibits a 11.251\% 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. Cn1c2c(c(=O)[nH]c1=O)C(c1ccc(O)cc1)C1=C(N2)c2ccccc2C1=O
b. COc1ccc(C=O)cc1CN1C(=O)c2ccccc2C1=O
Answer: b. COc1ccc(C=O)cc1CN1C(=O)c2ccccc2C1=O
