Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1cc2c(cc1OC)C(CCc1ccccc1)=NCC2
b: CC(=O)NCCn1c(SCC(=O)NCC2CCCO2)nc2ccccc2c1=O
c: CCCS(=O)(=O)c1nc(S(=O)(=O)c2ccc(C)cc2)c(NCCCN2CCOCC2)s1
d: COc1cccc(-c2cc(C(F)(F)F)nc(-n3cccn3)n2)c1
e: COC(=O)c1cc(Br)ccc1-c1ccc(/C=N/n2nnnc2N)o1
Answer: a. COc1cc2c(cc1OC)C(CCc1ccccc1)=NCC2
