Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: C=CCn1c(SCCC)nc(O)cc1=O
b: NC1C2CN3CCN(C2)CC1(c1ccccc1)C3
c: N#CC1=C(N)NC(SCC(=O)O)=C(C#N)C12CCCC2
d: O=C(NCC1CCCO1)c1ccc(CNS(=O)(=O)c2ccc(F)c(Cl)c2)cc1
e: COc1cccc(CN2CCN(Cc3nc(C(C)C)cs3)CC2CCO)c1
Answer: a. C=CCn1c(SCCC)nc(O)cc1=O
