Answer 1

Answer: (D)

Osteoporosis $\to$ Decrease in bone mass and higher chances of fractures with advancing age

• Skeletal system consists of a framework of bones and a few cartilages.
  
• Osteoporosis is defined as a low bone mass and microarchitectural deterioration of bone tissue, leading to enhanced bone fragility and a consequent increase in fracture risk.
• It occurs due to various fractures such as calcium deficiency, hyperparathyroidism, estrogen deficiency in females etc,
• Hence osteoporosis →→ Decrease in bone mass and higher chances of fractures with advancing age.
• So, the correct answer is 'Osteoporosis →→ Decrease in bone mass and higher chances of fractures with advancing age'.
