The deficiency of which nutrient causes night blindness?

Question of The Day19-06-2024

The deficiency of which nutrient causes night blindness? / किस पोषक तत्व की कमी से रतौंधी होती है?

Answer

Correct Answer : d ) Vitamin A / विटामिन A

Explanation :

Night blindness is mainly caused by the deficiency of Vitamin A.

This essential nutrient is important for maintaining healthy vision, especially in low light conditions.

Without enough vitamin A, the eyes cannot produce enough rhodopsin, a pigment needed for seeing in dim light.

Hence, (d) is the correct answer.

रतौंधी मुख्यतः विटामिन ए की कमी के कारण होती है।

यह आवश्यक पोषक तत्व स्वस्थ दृष्टि बनाए रखने के लिए महत्वपूर्ण है, खासकर कम रोशनी की स्थिति में।

पर्याप्त विटामिन ए के बिना, आंखें पर्याप्त रोडोप्सिन का उत्पादन नहीं कर पाती हैं, जो कम रोशनी में देखने के लिए आवश्यक वर्णक है।

अतः, (d) सही उत्तर है।
