Answer:2) vitamin C supplement
Step-by-step explanation:
The oesteoporosis is a disease of bones. In this the density of bones decreases and characterised by formation of pores on the bones. The bones become week and brittle. This may lead to fracture.
The vitamin C is also called as ascorbic acid. It is an antioxidant. It is used to control the blood pressure and prevent heart diseases. It should not be used for treatment of oesteoporosis.
Calcium supplements, Vitamin D supplement, and bed rests are the necessary treatments for oesteoporosis.
Calcium supplements will provide the density to the bones. Vitamin D will help in absorption of calcium from food. Bed rests will help in healing in case of fracture.
