Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a COC(=O)[C@@H](NCc1cccc(CN[C@H](C(=O)OC)C(C)C)c1)C(C)C
b NNC(=O)c1sc(-c2ccccc2)cc1N
c CCCCn1c(-c2ccc(F)c(F)c2)nc2cc3[nH]c(=O)c(C(C)C)nc3cc21
d CCOC(=O)CSC1=C(C#N)C(c2ccc(F)cc2)C(C(C)=O)=C(C)N1
Answer: b. NNC(=O)c1sc(-c2ccccc2)cc1N
