The correct Answer is:
To solve the question, we need to evaluate each statement one by one and determine whether they are true or false. Here’s a step-by-step breakdown: ### Step 1: Evaluate Statement 1 **Statement:** Neuroglial cells protect and support the neurons. **Evaluation:** This statement is **true**. Neuroglial cells (or glial cells) are indeed responsible for protecting and supporting neurons in the nervous system. ### Step 2: Evaluate Statement 2 **Statement:** Cartilage has a hard and non-pliable matrix rich in magnesium salts. **Evaluation:** This statement is **false**. Cartilage has a soft and pliable matrix, primarily composed of chondroitin sulfate, not magnesium salts. ### Step 3: Evaluate Statement 3 **Statement:** Smooth muscles are striated. **Evaluation:** This statement is **false**. Smooth muscles are non-striated, which distinguishes them from skeletal muscles that are striated. ### Step 4: Evaluate Statement 4 **Statement:** Chondrocytes are bone-forming cells. **Evaluation:** This statement is **false**. Chondrocytes are the cells that form cartilage, while osteoblasts are the cells responsible for forming bone. ### Step 5: Evaluate Statement 5 **Statement:** Biceps are parallely bundled. **Evaluation:** This statement is **true**. The muscle fibers in the biceps are arranged in a parallel fashion, which is characteristic of this type of muscle. ### Conclusion After evaluating all the statements, we find: - Statement 1: True - Statement 2: False - Statement 3: False - Statement 4: False - Statement 5: True ### Correct Option The only statements that are true are 1 and 5. Therefore, the correct option would be that statements 2, 3, and 4 are wrong. ### Final Answer The correct option is: **2, 3, and 4 are wrong.** ---
