Problem statement: Answer the multiple choice question.
Question: Which drug has a -2.794\% 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 additional words.
Options:
a COc1cccc(Nc2nc(-c3sc(NC(=O)c4ccccc4)nc3C)cs2)c1
b O=C(O)c1cc([N+](=O)[O-])c(N2CCCC2)c([N+](=O)[O-])c1
Answer: b. O=C(O)c1cc([N+](=O)[O-])c(N2CCCC2)c([N+](=O)[O-])c1
