Task: Answer the multiple-choice question.
Query: Which drug has a 16.586\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(NCCNC(=O)c1ccccc1[N+](=O)[O-])c1ccccc1[N+](=O)[O-]
b NC(=O)NC(CC(=O)Nc1cccnc1)c1cccc(Br)c1
c COc1ccc(CCN(C)C(=O)c2cc(=O)c3ccccc3o2)cc1OC
Answer: a. O=C(NCCNC(=O)c1ccccc1[N+](=O)[O-])c1ccccc1[N+](=O)[O-]
