Observe the flowchart with reference to joints and their examples. Choose the correct option that matches with the letters given in the boxes.

Step-by-step solution

Based on the classification of joints in the human body: 1. Joints are primarily classified into three structural types: Fibrous, Cartilaginous, and Synovial. 2. Fibrous joints do not allow any movement. An example of this is the flat skull bones which fuse end-to-end with the help of dense fibrous connective tissues to form Cranial sutures . Thus, A represents Cranial sutures. 3. The joint between adjacent vertebrae in the vertebral column is a Cartilaginous joint , which permits limited movement. Thus, B represen
