Answer: (B)

Verified step by step guidance

1. Understand the types of joints: Joints are classified based on their structure and function. The main types include fibrous, cartilaginous, and synovial joints.
2. Identify the role of each joint type: Fibrous joints (e.g., syndesmosis and gomphosis) are generally immovable. Cartilaginous joints (e.g., synchondrosis and symphysis) allow more movement than fibrous joints but less than synovial joints.
3. Focus on growth in long bones: During childhood, long bones grow at the epiphyseal plate, which is a type of cartilaginous joint.
4. Recognize the specific joint type: The epiphyseal plate is a synchondrosis, a temporary cartilaginous joint where hyaline cartilage is eventually replaced by bone.
5. Conclude with the correct joint type: Synchondrosis is the joint type primarily responsible for allowing growth in long bones during childhood.
