Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COCc1c(Br)c(C)nc(OCC(=O)O)c1C#N
b COc1ccc(OC)c2[nH]c(=O)c(CCNS(=O)(=O)c3ccc(C)cc3)cc12
c O=C(C(Cl)Cl)N1CCN(c2ccccn2)CC1
d COCCCn1c(SCC(=O)c2ccccc2)nc2ccccc2c1=O
Answer: a. COCc1c(Br)c(C)nc(OCC(=O)O)c1C#N
