Task: Answer the multiple-choice question.
Question: Which compound exhibits a 4.937\% 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] CCCc1[nH]nc2c1C(CCC)C(C#N)=C(N)O2
[b] CN(Cc1ccccc1)c1nc(-c2cccc([N+](=O)[O-])c2)nc2ccccc12
[c] COc1ccc(N2C(=O)S[C@@H]3CS(=O)(=O)C[C@@H]32)cc1
[d] COc1ccc(S(=O)(=O)NC(N)=NCCc2ccccc2)cc1
Answer: b. CN(Cc1ccccc1)c1nc(-c2cccc([N+](=O)[O-])c2)nc2ccccc12
