[[1]] structure of prokaryotes is analogous to the lysosome.
 

Concept: Lysosomes are the suicidal bags or disposal units of cells that digest and remove the wear and tear organelles and molecules from the cell. 
The space between inner (plasma) and outer membranes of Gram-negative bacteria and spirochetes is called the periplasmic space which contains enzymes for assembly of the cell wall and membrane components, various degradative enzymes that serve as lysosomal enzymes and digest the wear and tear portion of the cell.
Hence, periplasmic space is the correct option.
