Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCOc1ccc(S(=O)(=O)NCCC(=O)N2CC(C)CC(C)C2)cc1
b) Nc1ccc2c(c1)C(=O)c1ccccc1-2
c) COc1ccc2[nH]c(O)c(N=O)c2c1
d) CC(=O)c1cccc(NC(=O)NNC(=O)c2ccc(-c3ccccc3)cc2)c1
Answer: c. COc1ccc2[nH]c(O)c(N=O)c2c1
