Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCOc1ccc(CCNC(=O)CS(=O)Cc2nc(-c3ccc(C)cc3)oc2C)cc1OCC
b: Cc1cccn2c(=O)c(C=O)c(Nc3ccc(S(N)(=O)=O)cc3)nc12
c: COc1ccc(C2=CC(=O)CC(C)(C)C2)cc1OC
d: O=C(N/N=C/c1c(O)n(-c2ccc(Cl)cn2)c(=O)c2ccccc12)c1ccncc1
Answer: d. O=C(N/N=C/c1c(O)n(-c2ccc(Cl)cn2)c(=O)c2ccccc12)c1ccncc1
