Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cn1c(=O)c2c(ncn2CC(=O)N2CCCCCC2)n(C)c1=O
b: CC1(C)C(=O)C2(C(=O)NCc3ccccc3)CCC1C2
c: C=CCN(c1ccc(C(=O)NCCSc2ccccc2)cc1)S(C)(=O)=O
d: Cn1ccnc1SCC(=O)NC1CC1
Answer: b. CC1(C)C(=O)C2(C(=O)NCc3ccccc3)CCC1C2
