Answer:
Option a.
Explanation:
Osteoporosis, which truly implies permeable bone, is a malady wherein the thickness and nature of bone are decreased. As bones become progressively permeable and delicate, the danger of break is extraordinarily expanded.
The loss of bone happens quietly and dynamically. Normally, there are no side effects until the first bone fracture happens.
The susceptibility of the disease increases if any one in the family is suffering from this disease or a family has a history of osteoporosis.
