Consider the following statements regarding cell wall composition : 1. Bacterial cell wall is made of peptidoglycan. 2. Fungal cell wall is made of cellulose. 3. Animals lack cell wall and have extracellular matrix made up of sugar and proteins. Select the correct answer using the code given below :

The correct answer is Option C (1 and 3 only) based on the biological composition of cell structures:

• Statement 1 is correct: The bacterial cell wall is primarily composed of peptidoglycan (also called murein), a polymer consisting of sugars and amino acids that provides structural support.
• Statement 2 is incorrect: While plant cell walls are made of cellulose, fungal cell walls are primarily composed of chitin, a tough, nitrogen-containing polysaccharide.
• Statement 3 is correct: Animal cells are unique among multicellular organisms as they lack a cell wall. Instead, they possess an extracellular matrix (ECM), which is a complex meshwork of proteins (like collagen) and carbohydrates (proteoglycans) that provides structural support and helps in cell-to-cell communication.
