A common problem of the land-locked states of Africa is that?
Answer Details
Land-locked states of Africa are countries that do not have direct access to the sea. One common problem they face is that they are dependent on their coastal neighbors for access to seaports and international trade routes. This often leads to higher transportation costs for imported goods, which can affect their economies negatively. Additionally, these countries may also have limited access to resources, which can further hinder their development. Therefore, the correct option is "they are dependent on the coastal neighbors for access to the sea".
