Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.462\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CCN(C(=O)CSc1ncccc1C(=O)Oc1cccc([N+](=O)[O-])c1)c1cccc(C)c1
b.) CC1(c2ccccc2)NC(=O)N(CC(=O)Nc2ccc(S(=O)(=O)Nc3ncccn3)cc2)C1=O
Answer: a. CCN(C(=O)CSc1ncccc1C(=O)Oc1cccc([N+](=O)[O-])c1)c1cccc(C)c1
