• C. Synovial membrane
• D. Mucous membrane

Answer: (B)

Verified step by step guidance

1. Understand the function of membranes in the body: Membranes are layers of tissue that cover or line surfaces and cavities. They serve various functions, such as protection, secretion, and absorption.
2. Review the types of membranes: The four main types of membranes in the body are cutaneous, mucous, serous, and synovial membranes. Each has distinct characteristics and locations.
3. Focus on the serous membrane: Serous membranes are thin, double-layered membranes that secrete serous fluid to reduce friction between organs. They are found lining cavities and covering organs, such as those in the digestive system.
4. Eliminate incorrect options: Cutaneous membranes are the skin, synovial membranes are found in joints, and mucous membranes line cavities that open to the exterior (e.g., respiratory and digestive tracts). These do not cover the surfaces of most digestive organs.
5. Conclude that the serous membrane is the correct answer: The serous membrane specifically covers the surfaces of most digestive organs, such as the stomach and intestines, and helps reduce friction during organ movement.
