Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCOc1ccc(C2CC(c3ccccc3C)n3ncnc3N2)cc1
b: CCOC(=O)CSc1nc2c(sc(=S)n2-c2ccccc2)c(=O)[nH]1
c: O=P(Cc1nnco1)(c1ccccc1)c1ccccc1
d: CCOc1ccccc1N(CC(=O)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1)S(=O)(=O)c1ccccc1
e: COc1ccc(-c2[nH]nc3c2C(c2ccsc2)C(C#N)=C(N)O3)cc1
Answer: a. CCOc1ccc(C2CC(c3ccccc3C)n3ncnc3N2)cc1
