Correct Answer : Option (B) - Malabar
In 1789 Tipu Sultan sent forces onto the Malabar Coast to put down a rebellion. Many people fled to Travancore, a state independent of Mysore and to Cochin, a state paying tribute to Tipu, in the wake of his advance. To follow them, Tipu began, in the fall of 1789 to build up troops at Coimbatore in preparation for an assault on the Nedumkotta, a fortified line of defence built by Dharma Raja of Travancore to protect his domain.
