Task: Answer the multiple choice question.
Query: Which drug has a -3.689\% 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 additional words.
Options:
(a) O=C(NNC(=O)c1ccccc1-c1ccccc1C(=O)O)c1cccc([N+](=O)[O-])c1
(b) O=C(NCc1ccccn1)Nc1ccccc1C(F)(F)F
Answer: a. O=C(NNC(=O)c1ccccc1-c1ccccc1C(=O)O)c1cccc([N+](=O)[O-])c1
