Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(NCCc1c[nH]c2ccccc12)C(=O)Nc1ccccc1
(b) Cc1ccc(S(=O)(=O)NC(C)C(=O)Nc2ccc(C(N)=O)cc2)cc1
(c) O=C(NCC1CCCO1)c1cccnc1Nc1ccccc1F
(d) CN1c2ccc([N+](=O)[O-])cc2C(C)(C)C12C=Cc1cc(C(=O)O)ccc1O2
Answer: d. CN1c2ccc([N+](=O)[O-])cc2C(C)(C)C12C=Cc1cc(C(=O)O)ccc1O2
