Lord Ganesha

Maha Shivaratri is a major Hindu festival dedicated to the worship of Lord Shiva. It is celebrated every year on the 14th night of the dark half of the month of Phalguna (February-March). The festival is observed by fasting, meditating on Shiva, and performing pujas (worship rituals). Devotees also visit Shiva temples and offer prayers and offerings to the deity.

Lord Shiva is one of the three main deities of Hinduism, along with Brahma and Vishnu. He is the god of destruction and transformation. He is also the god of dance and music. Shiva is often depicted as a wandering ascetic, covered in ash and wearing a tiger skin. He is also associated with the lingam, a phallic symbol.

Maha Shivaratri is a time for Hindus to renew their devotion to Shiva and to seek his blessings. It is also a time to reflect on the cycle of life and death. The festival is a reminder that death is a natural part of life and that it should not be feared.

The other options are incorrect because they are not the main deities of Hinduism. Lord Vishnu is the god of preservation and protection. Goddess Durga is the goddess of power and strength. Lord Ganesha is the god of wisdom and prosperity.
