The correct answer is (a) 23rd March.
Kisan Diwas, also known as Farmers’ Day, is a national holiday in India that is celebrated on 23 March every year. The day commemorates the birth anniversary of Chaudhary Charan Singh, who was the fifth Prime Minister of India and a prominent leader of the Bharatiya Kisan Union (BKU).
Kisan Diwas is an occasion to celebrate the contributions of farmers to the Indian economy and to highlight the challenges that they face. On this day, various events and programs are organized across the country to honor farmers and to raise awareness about their issues.
The other options are incorrect because they are not the dates on which Kisan Diwas is celebrated.
