The correct answer is: a) Remote areas.
Limited accessibility to some tourist destinations due to poor infrastructure is a challenge for Assam’s tourism sector, particularly in remote areas. This is because remote areas are often located in mountainous or forested regions, which can make it difficult to build roads and other infrastructure. Additionally, remote areas may not have the same level of public transportation as more developed areas, which can make it difficult for tourists to get around.
Hill districts are also a challenge for Assam’s tourism sector, due to their remoteness and difficult terrain. However, they offer a unique and beautiful landscape that attracts many tourists. Border regions are also a challenge for Assam’s tourism sector, due to security concerns. However, they offer a unique glimpse into the culture and history of the region. Urban centers are the most developed areas of Assam, and they have the best infrastructure for tourism. However, they can be crowded and noisy, which can be off-putting to some tourists.
In conclusion, the correct answer is: a) Remote areas.
