Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the classification of joints in the human body. Joints are categorized into three main types based on their structure and function: fibrous joints, cartilaginous joints, and synovial joints.
2. Step 2: Review the characteristics of fibrous joints. These joints are connected by dense connective tissue and allow little to no movement. Examples include sutures in the skull.
3. Step 3: Examine cartilaginous joints. These joints are connected by cartilage and allow limited movement. Examples include intervertebral discs and the pubic symphysis.
4. Step 4: Study synovial joints. These joints are characterized by a synovial cavity filled with fluid, which allows free movement. Examples include the knee, shoulder, and hip joints.
5. Step 5: Analyze the figure provided in the problem and determine the structural features of the joints depicted. Compare these features to the descriptions of fibrous, cartilaginous, and synovial joints to classify them correctly.
