Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) O=C(Cn1cnc2cc([N+](=O)[O-])ccc2c1=O)Nc1ccc(N2CCOCC2)cc1
b.) COC1=CC=C2[C@H]3Cc4ccc(OC)c5c4[C@@]2(CCN3C)[C@H]1O5.Cl
c.) O=c1[nH]c(C2CCN(S(=O)(=O)Cc3ccccc3)CC2)nc2c1nnn2Cc1cccc(Cl)c1
d.) Cc1ccc(/C=N/n2c(=O)c(C(C)(C)C)nn3cnnc23)cc1
e.) O=C1c2ccccc2N(Cc2ccc(Cl)cc2)C2=NCCN12
Answer: e. O=C1c2ccccc2N(Cc2ccc(Cl)cc2)C2=NCCN12
