Final Answer : A, Explanation :  The time hypothesis suggests that areas that have been ecologically stable for long periods have more species because they have had more time for speciation to occur. Canada, being at a higher latitude, has experienced more recent and severe glaciations compared to the tropical regions of Brazil, Cameroon, Papua New Guinea, and Burundi. These glaciations would have periodically wiped out species or forced them to migrate, leading to lower species richness today.
