Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1cc(C(=O)OCC(=O)c2c(N)n(C)c(=O)n(C)c2=O)ccc1OCCC(C)C
b: O=C(N/N=C/c1cccs1)c1[nH]ncc1Br
c: COc1ccc(-n2c(SCC(=O)NCC3CCCO3)nc3c(c2=O)SC(C)C3)cc1
Answer: b. O=C(N/N=C/c1cccs1)c1[nH]ncc1Br
