Solution
The correct option is B Lysosome
- Lysosomes are small vesicles containing hydrolyzing enzymes and surrounded by a single membrane of up to 100 nm thickness.
- Nucleus and mitochondria are double membranes bound to cell organelles.
- The endoplasmic reticulum is a system of membrane-lined channels found in all eukaryotic cells except mature erythrocytes. It constitutes more than 30 to 60 percent of the total cell membrane. The membrane system of the endoplasmic reticulum is double-membraned and is often connected with the outer membrane of the nuclear envelope.
Thus, the correct answer is (A).
