Explanation:

• Option A: Sticky ends are overhanging sequences of DNA after restriction enzyme digestion, not for immune stimulation.
• Option B: DNA ligase joins DNA fragments, related to DNA manipulation, not immunity.
• Option C: Monoclonal antibodies can be used to stimulate or modulate an organism's immune system (e.g., in therapies, diagnostic tools, or triggering immune responses).
• Option D: Restriction enzymes cut DNA, used in molecular biology for DNA manipulation, not immune stimulation.
