The correct answer is: A. Vaisaha
Nirjala Ekadashi is a Hindu festival that is celebrated on the eleventh day of the waxing moon in the month of Vaisakha. It is a day of fasting and penance, and is considered to be one of the most important days of the year for Hindus.
The festival is observed in different ways by different people. Some people fast for the entire day, while others only fast for a few hours. Some people also take a vow of silence on this day.
The festival is believed to have originated in the Mahabharata. According to the story, the Pandavas were exiled to the forest for 12 years. During their exile, they observed Nirjala Ekadashi on the advice of their guru, Dronacharya.
The festival is also associated with the story of Krishna and Indra. According to the story, Indra, the king of the gods, was once very proud. He insulted the sage Durvasa, who cursed him to become a mortal. Indra then begged Durvasa to forgive him, and Durvasa agreed on the condition that Indra would observe Nirjala Ekadashi every year.
Nirjala Ekadashi is a day of great significance for Hindus. It is a day to cleanse the mind and body, and to seek forgiveness for one’s sins. It is also a day to remember the sacrifices of the Pandavas, and to pray for their blessings.
