Which vitamin is synthesised in the presence of sunlight in our body?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. Vitamin D.

  • Vitamin D synthesis in the human body relies on sunlight. Ultraviolet B (UVB) rays trigger the conversion of 7-dehydrocholesterol in the skin to vitamin D3.
  • This process is crucial for maintaining calcium and phosphorus balance, vital for bone health. Factors like skin pigmentation, sunscreen use, and geographic location influence vitamin D production. Insufficient sunlight exposure can lead to vitamin D deficiency, necessitating dietary supplements or fortified foods.
