Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] S=C(Nc1ccc2cn[nH]c2c1)Nc1ccc(Cl)cc1Cl
[b] Oc1[nH]c2ccc(Br)cc2c1N=Nc1nn[nH]n1
[c] Cc1occc1C(=O)NCc1ccccc1F
[d] CCc1nnc(SCc2cn3c(C)cc(C)nc3n2)n1N
Answer: a. S=C(Nc1ccc2cn[nH]c2c1)Nc1ccc(Cl)cc1Cl
