Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.228\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC1=NN(C(=O)c2ccccc2)C(O)(c2ccc(Br)cc2)C1
b O=C(Nc1nccs1)c1ccc(-c2ccc([N+](=O)[O-])cc2)o1
c O=Cc1ccc(OCCCOc2cccc3cccnc23)cc1
d CNc1ccc([N+](=O)[O-])cc1C(=O)O
e Cc1cccc(CN2CCCC(C(=O)N3CCc4ccccc4C3)C2)c1.O=C(O)C(=O)O
Answer: d. CNc1ccc([N+](=O)[O-])cc1C(=O)O
