Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC(/C=N\Nc1nnc2c(n1)[nH]c1c(C)cccc12)=C\c1ccco1
b Cn1c(C(=O)Nc2ccc3c(c2)OCCO3)cc2c(=O)n(C)c3ccccc3c21
c O=C(CCN1C(=O)c2ccccc2C1=O)NC(=S)Nc1cccc(Cl)c1
d COC(=O)/C=c1/s/c(=C(\C#N)C(=O)NCc2ccco2)n(-c2ccccc2)c1=O
Answer: d. COC(=O)/C=c1/s/c(=C(\C#N)C(=O)NCc2ccco2)n(-c2ccccc2)c1=O
