Options
A Presence of ribosomes on its surface
Correct Answer
B Ability to synthesize lipids
C Lack of membrane structure
D Absence of any metabolic role
Correct Answer

Option A is the correct answer.

Detailed Explanation

The rough endoplasmic reticulum (RER) is studded with ribosomes on its cytosolic surface, giving it a 'rough' appearance under a microscope. These ribosomes synthesize proteins that are inserted into the RER lumen or membrane. Smooth ER lacks ribosomes.
