Task: Answer the multiple choice question.
Question: Which drug has a -1.348\% 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) CNC1=C([N+](=O)[O-])CC([N+](=O)[O-])=C(N2CCN(C(=O)Nc3cccc(C(F)(F)F)c3)CC2)N1C
(b) Cc1ccccc1NC(=O)c1cccc(NC(=O)c2c(C(=O)O)cccc2[N+](=O)[O-])c1
Answer: b. Cc1ccccc1NC(=O)c1cccc(NC(=O)c2c(C(=O)O)cccc2[N+](=O)[O-])c1
