Answer/Explanation:
Recall:
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1

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.
