The correct answer is: d) Were frequently reorganized.
The administrative divisions created by the British in Andhra Pradesh were frequently reorganized. This was because the British were constantly trying to find the best way to govern the region. They experimented with different systems, and they often changed the boundaries of the districts. This made it difficult for people to keep track of the administrative divisions, and it also made it difficult for the British to effectively govern the region.
Option a) is incorrect because the administrative divisions created by the British in Andhra Pradesh did not form the basis of present-day districts. The present-day districts of Andhra Pradesh were created after India gained independence from the British.
Option b) is incorrect because the administrative divisions created by the British in Andhra Pradesh were not purely based on linguistic boundaries. The British took into account a number of factors when creating the administrative divisions, including linguistic boundaries, but they also considered other factors such as geography and history.
Option c) is incorrect because the administrative divisions created by the British in Andhra Pradesh did not reflect traditional regional identities. The British created the administrative divisions based on their own needs, and they did not take into account the traditional regional identities of the people of Andhra Pradesh.
