Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the three main types of joints in the human body: fibrous, cartilaginous, and synovial. Fibrous joints are immovable or allow very limited movement, such as sutures in the skull. Cartilaginous joints allow limited movement and are found in areas like the intervertebral discs and pubic symphysis.
2. Step 2: Recognize that synovial joints are the most movable type of joint in the human body. They are characterized by the presence of a joint cavity filled with synovial fluid, which reduces friction and facilitates movement.
3. Step 3: Evaluate the statement 'Fibrous joints allow for a wide range of movement.' This is incorrect because fibrous joints are designed for stability rather than mobility.
4. Step 4: Assess the statement 'Cartilaginous joints are only found in the skull.' This is incorrect because cartilaginous joints are found in various parts of the body, such as the spine and pelvis, not just the skull.
5. Step 5: Analyze the statement 'All joints in the body contain a joint cavity filled with synovial fluid.' This is incorrect because only synovial joints have a joint cavity filled with synovial fluid; fibrous and cartilaginous joints do not.
