Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.005\% 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 CCc1ccc(NC(=O)N2CCN(C(=O)C3CCCO3)CC2)cc1
b CC(Oc1cc(F)ccc1[N+](=O)[O-])C(=O)N(C)CC(=O)Nc1ccccc1C(F)(F)F
Answer: a. CCc1ccc(NC(=O)N2CCN(C(=O)C3CCCO3)CC2)cc1
