Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 12.749% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COc1ccccc1/C=C1/C(=O)N(c2ccc([N+](=O)[O-])cc2)N=C1C
b. CS(=O)(=O)c1ccccc1C(=O)Nc1ccc(-c2nc3ccccc3o2)cc1
Answer: a. COc1ccccc1/C=C1/C(=O)N(c2ccc([N+](=O)[O-])cc2)N=C1C
