The correct answer is: a) Lord Krishna.
Doul Utsav is a Hindu festival celebrated in the month of Falgun (February-March) in the Indian subcontinent. It is also known as Dol Jatra, Dol Purnima, Holi Utsab, or simply Holi. The festival marks the beginning of spring and the end of winter. It is also a time to celebrate the victory of good over evil.
Doul Utsav is associated with the worship of Lord Krishna. According to Hindu mythology, Lord Krishna was born in the month of Falgun. He was a mischievous child who loved to play pranks on people. One day, he played a prank on his aunt, Yashoda, by stealing her clothes while she was bathing. Yashoda was furious and chased Krishna all over the village. When she finally caught him, she beat him with a stick. Krishna cried and cried, and his tears turned into a river of colors. This is why people celebrate Doul Utsav by throwing colored powder and water at each other.
The other options are incorrect because they are not associated with Doul Utsav. Lord Shiva is a Hindu god who is associated with destruction and creation. Goddess Durga is a Hindu goddess who is associated with power and strength. Goddess Lakshmi is a Hindu goddess who is associated with wealth and prosperity.
