Option 1 -> Substituting a sedentary lifestyle with an active one would actually prevent osteoporosis, not cause it.
Option 2 -> The passage states that fizzy drinks are "often a substitute for a glass of milk," causing children to miss calcium and vitamin D, leading to brittle bones and osteoporosis risk.
Option 3 -> The passage mentions fruits and vegetables together as sources of calcium for prevention, not substitution causing the disease.
Option 4 -> Both sunlight and calcium are mentioned as preventive measures, not as substitutes that cause osteoporosis.
Hence, Option 2 -> The passage explicitly states that when children substitute milk with soft drinks, they miss out on essential calcium and vitamin D needed to build strong bones, making them prone to osteoporosis later in life -> correct
