Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCOC(=O)c1cnc(-n2nc(C)cc2C)nc1N(CC)CC
b CN(C)/C=C/C(=O)c1ccc(F)cc1
c O=C(O)/C=C/C(=O)Nc1ccc(N2CCOCC2)nc1N1CCOCC1
d C/C=C/c1ccc(OCCCn2cncn2)c(OC)c1
e CC1(C)CC(=O)N(Cc2ccccc2)C(=O)C1
Answer: a. CCOC(=O)c1cnc(-n2nc(C)cc2C)nc1N(CC)CC
