• Rheumatic arthritis is an example of an autoimmune disease that affects the joints.
• The autoimmune diseases are generated due to the activity of the immune cells against the self-cells. 
• The immune cells are not able to distinguish between the self and the non-self cells. 
• There is no known antigen that can provoke the immune cells to show an immune response against the cells of the body. 

Gout is a clinical condition. Gout is a kind of arthritis. It can cause an attack of sudden burning pain, stiffness and swelling in a joint, usually a big toe. These attacks can happen over and over unless gout is treated. Over time, they can harm your joints, tendons and other tissues. Gout is most common in men. Gout is caused by too much uric acid in the blood. Most of the time, having too much uric acid isn't harmful. Many people with high levels in their blood never get gout. But when uric acid levels in your blood are too high, the uric acid may form hard crystals in your joints. It's not a degenerative disease, infectious disease and deficiency disease. Thus, option D is correct.

Still's disease is an inflammation of joints causing arthritis which produces symptoms such as fever, rash, and joint pains. If it is not treated, the inflammation may destroy joints particularly the wrist joints. Steroids are used in treating this rare disease.

So, the correct answer is 'Arthritis'

Both statements 1 & 2 are correct with respect to the skeletal joint.

Gouty arthritis is an inherited disorder of purine metabolism, occurring especially in men, gout is related to diet that giving rise to severe arthritis called gouty arthritis, a person suffering from gout should avoid meat. Purine is a nitrogenous waste.

• Muscle is a  bundle of fibrous tissue in a body that has the ability to contract, producing movement in or maintaining the position of parts of the body.
• The total number of muscles in the human body comes in the range of 640-850.
• Muscles appear in red color due to a pigment called myoglobin. It receives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the oxygen is used in cellular respiration to produce energy. Hence myoglobin occurs in red muscle fibers. So, the correct answer is 'Red muscle fibers'.

• Collagen is a type of protein fibre found abundantly throughout our body.
•  It provides strength and protects many different areas of the body, including the skin.
•  These White fibres, made up of collagen are white and shining which are strong, non-elastic and tough. 
• More specifically, collagen is found in our various types of connective tissues such as cartilage, tendons, bones, and ligaments. Hence, collagen fibres are white.

• Muscle is a  bundle of fibrous tissue in a body that has the ability to contract, producing movement in or maintaining the position of parts of the body.
  
• Muscles appear in red color due to a pigment called myoglobin. Myoglobin receives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the oxygen is used in cellular respiration to produce energy.
• Cytochrome is a protein associated with the inner membrane of mitochondria. As the number of mitochondria is abundant in red fibers thus represents the abundance of cytochrome in red muscles. 
• Hence red muscles are rich in myoglobin and cytochrome.
• So, the correct answer is 'Myoglobin and cytochrome'.
