Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CNC(=S)N(CCc1c(C)[nH]c2ccc(C)cc12)Cc1cccnc1
(b) CC(Cc1ccccc1)NC(=O)Cc1ccc(N(C)C)cc1
(c) CC12CC(NC(=O)N1c1cccc(C(=O)N3CCCCC3)c1)c1ccccc1O2
(d) CC1=C(C(=O)OCC(Br)(Br)Br)C(c2cccc([N+](=O)[O-])c2)NC(=O)N1CCCC(=O)O
Answer: d. CC1=C(C(=O)OCC(Br)(Br)Br)C(c2cccc([N+](=O)[O-])c2)NC(=O)N1CCCC(=O)O
