Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.495\% 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 additional words.
Options:
a NS(=O)(=O)c1cccc(NC(=O)CCS(=O)(=O)c2ccc(Cl)cc2)c1
b N=C1c2ccccc2CN1c1cccc([N+](=O)[O-])c1
c CC(c1ccco1)N(C(=O)c1ccccc1NS(=O)(=O)c1cccc([N+](=O)[O-])c1)c1ccccn1.Cl
Answer: b. N=C1c2ccccc2CN1c1cccc([N+](=O)[O-])c1
