The correct answer is D. Mitochondria.
Mitochondria are organelles found in eukaryotic cells that are responsible for energy production. They contain enzymes that are involved in the process of cellular respiration, which is the process by which cells convert food into energy.
Dictyosomes are organelles that are involved in the production of cell membranes and other membrane-bound organelles. They do not contain enzymes for cellular respiration.
Endoplasmic reticulum is a network of tubules and sacs that is involved in the synthesis of proteins and lipids. It does not contain enzymes for cellular respiration.
Lysosomes are organelles that are involved in the breakdown of cellular components. They do not contain enzymes for cellular respiration.
