Which region is the Sarhul festival, orgainsed on 1st April 2025, particularly significant in?

The correct option is The Chhotanagpur region and Jharkhand.

Sarhul is one of the most famous and significant tribal festivals celebrated in India, particularly by the tribal communities such as the Oraon, Munda, and Ho tribes.
These tribes are primarily settled in the Chhotanagpur plateau region, which spans across Jharkhand and parts of its neighboring states like Odisha, Bihar, and West Bengal.

The festival marks the beginning of the tribal New Year and is celebrated during the spring season (usually in the Hindu month of Chaitra) when the Saal trees (Shorea robusta) get new leaves and flowers. The term "Sarhul" translates to "worship of trees" or "Sal-worship." During this festival, tribal people worship nature, specifically the Saal tree, seeking blessings for a good harvest and prosperity, making it deeply rooted in the cultural and agricultural landscape of the Chhotanagpur region and Jharkhand.
