Task: Answer the multiple choice question.
Question: Which compound exhibits a 7.957\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C1c2ccc([N+](=O)[O-])cc2S(=O)(=O)N1Cc1ccccc1
[b] Cc1cc2nncn2c2ccccc12
[c] Cc1cc(C)c2nc(SCC(=O)Nc3ccc(S(=O)(=O)N4CCCC4)cc3)c(C)cc2c1
[d] Cn1cc(C(=O)N/N=C/c2cc(Br)cs2)c2ccccc21
Answer: a. O=C1c2ccc([N+](=O)[O-])cc2S(=O)(=O)N1Cc1ccccc1
