Task: Answer the multiple-choice question.
Question: Which compound has a 13.718\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CC(C)(C)Nc1nc(Cl)nc(N(C#N)CN2C(=O)c3ccccc3S2(=O)=O)n1
b: CO/N=C/Cc1c([N+](=O)[O-])c(C)nn1C
c: O=C(N/N=C/c1ccccc1C(=O)O)c1ccccc1Br
d: CC(C)[C@H](NC(N)=O)C(=O)Nc1cccc([N+](=O)[O-])c1
Answer: b. CO/N=C/Cc1c([N+](=O)[O-])c(C)nn1C
