Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCC(=O)Nc1ccc(C(=O)NCCCn2ccnc2)cc1
b O=C(NC(Cc1c[nH]c2ccccc12)C(=O)N/N=C/c1ccc(Br)cc1)c1cccs1
c Cc1cc(C)c(S(=O)(=O)NCCn2ccc3ccccc32)c(C)c1
d NC(=O)C1(c2ccccc2)OC1c1ccccc1
Answer: b. O=C(NC(Cc1c[nH]c2ccccc12)C(=O)N/N=C/c1ccc(Br)cc1)c1cccs1
