Answer 1

The correct option is B Osteoporosis-decrease in bone mass and higher chances of fractures with advancing age

$1)$ Muscular dystrophy - age related shortening of muscles is incorrect.
Muscular dystrophy is progressive degeneration of skeletal muscle mostly due to genetic disorder.

$2)$ Osteoporosis-decrease in bone mass and higher chances of fractures with advancing age is correct.

$3)$ Myasthenia gravis - auto immune disorder which inhibits sliding of myosin filaments is incorrect. Myasthenia gravis is an auto immune disorder affecting neuromuscular junction leading to fatigue, weakening and paralysis of skeletal muscle.

$4)$ Gout - Inflammation of joints due to extra deposition of calcium is incorrect. Gout is inflammation of joints due to accumulation of uric acid crystals.
