The correct Answer is:
To solve the question regarding the assertion and reason about amphiarthrosis joints, we will analyze both statements step by step. ### Step 1: Analyze the Assertion **Assertion:** Maximum movement is possible at the amphiarthrosis joint. - **Explanation:** Amphiarthrosis joints are known for their limited mobility. They allow slight movement but are not designed for maximum movement. An example of an amphiarthrosis joint is the intervertebral discs between the vertebrae, which provide some flexibility but not extensive movement. ### Step 2: Analyze the Reason **Reason:** Such joints are also called synovial joints and have almost frictionless movement due to synovial fluid. - **Explanation:** This statement is incorrect because amphiarthrosis joints are not synovial joints. Synovial joints are characterized by a greater range of motion and contain synovial fluid, which reduces friction. Amphiarthrosis joints, on the other hand, are typically cartilaginous joints and do not have the same features as synovial joints. ### Step 3: Conclusion Based on the analysis: - The assertion is **false** because amphiarthrosis joints do not allow maximum movement; they allow limited movement. - The reason is also **false** because amphiarthrosis joints are not synovial joints and do not have frictionless movement due to synovial fluid. ### Final Answer Both the assertion and the reason are false, so the correct option is: **(d) If both Assertion and Reason are false.** ---
