The correct answer is the one that shows a bone having the most porous appearance inside.
Osteoporosis is a disease of the different types of bone tissue that make up bone ("cortical bone" and "trabecular bone").
It is a disease that is related to a decrease in the amount of bone tissue in the bones and / or an alteration of its structure: thinning of the cortex and bone trabeculae that become porous.
The cause is an imbalance between the deficit activity of osteoblasts and normal osteoclastic bone resorption.
