• B. II alone is correct
• C. III alone is incorrect
• D. I alone is incorrect
• E. II alone is incorrect

Answer 1

The correct option is C III alone is incorrect

• Osteoporosis is a bone disease that occurs when the body loses too much bone, makes too little bone, or both. As a result, bones become weak and may break from a fall or, in serious cases, from sneezing or minor bumps. Osteoporosis means “porous bone.”
  
• Osteoporosis can be caused due to deficiency of vitamin D, while osteomalacia is caused by a deficiency in calcium and phosphorus.
• Hence Osteoporosis is characterized by deterioration of the bone due to deficiency of phosphorous is an incorrect statement.
• So, the correct answer is 'III alone is incorrect'.
