Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1cc2cc(C(=O)O)n(C)c2c(OC)c1OC
b: Cc1ccc(-c2nc3[nH]c(=O)cc(NC(=O)c4cccs4)n3n2)cc1
c: Cc1c(OC(=O)c2ccc([N+](=O)[O-])cc2)c2c(c[n+]1C)COC(C)(C)OC2.[I-]
d: C/C(N)=C(/C#N)C(=O)CSc1nnc(Nc2ccccc2)s1
Answer: b. Cc1ccc(-c2nc3[nH]c(=O)cc(NC(=O)c4cccs4)n3n2)cc1
