Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1cc(NS(=O)(=O)c2ccc(NC(=O)/C(=C/c3ccccc3Cl)NC(=O)c3ccccc3)cc2)nc(OC)n1
b: O=CNC(Cc1ccccc1)C(=O)O
c: COc1cc(NC(=O)c2cccnc2SC)cc(OC)c1OC
d: COc1ccc(OCCCC(=O)Nc2ccc(N3CCCCC3)cc2)cc1.Cl
Answer: b. O=CNC(Cc1ccccc1)C(=O)O
