Answer 1

The correct answer is Sun light.

Key Points

Vitamin D is produced in the skin in response to sunlight exposure, specifically UVB rays.
Sunlight is a major source of Vitamin D, which is essential for the absorption of calcium and phosphate in the body.
Regular exposure to sunlight can help maintain adequate Vitamin D levels, which is crucial for bone health.
Approximately 10-30 minutes of midday sunlight exposure several times a week is usually sufficient for most people.
