The native State of Tripura became involved in the Freedom Movement early in the 20th century because

The correct option is B because of Tripura's unique geographical and political relationship with Bengal. During the early 20th century, especially following the Partition of Bengal in 1905, the state became a safe haven for anti-British revolutionaries. The kings of Tripura, who maintained close cultural and personal ties with the intellectual elite of Bengal, often provided tacit support or turned a blind eye to these activists. This allowed revolutionary groups like the Anushilan Samiti and Jugantar to use the hilly terrain of Tripura to hide from the British police, establish training camps, and coordinate their activities, thereby drawing the native state directly into the larger Indian freedom struggle.
