Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CN(C)c1cc[n+](Cc2ccccc2)cc1.[Br-]
b CCCN1C2CCCC1CC(NC(=O)c1ccccc1OCC)C2
c O=C(Nc1ccc(N2CCCCCC2)cc1)c1ccc[nH]1
d CN(C)CCCNc1ccc(-c2cc(Nc3cccc(Cl)c3)ncn2)cn1
e CSC(=O)CC(=O)NC(=O)c1ccccc1
Answer: c. O=C(Nc1ccc(N2CCCCCC2)cc1)c1ccc[nH]1
