Solution

The correct option is B
Ribosomes are absent on its membrane

Smooth endoplasmic reticulum is a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface and are devoid of ribosomes. The rough endoplasmic reticulum is studded with ribosomes. Lysosomes are spherical structures that contain hydrolytic enzymes. Mitochondria are involved in cellular respiration.
