Problem statement: Answer the multiple choice question.
Question: Which drug has a 9.599\% 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 COc1ccc2c([N+](=O)[O-])c(N3CCCC3)[nH]c2c1
b CCOC(=O)C1CCN(CCC(=O)Nc2ccc(C)c(C)c2)CC1
Answer: a. COc1ccc2c([N+](=O)[O-])c(N3CCCC3)[nH]c2c1
