Answer:
correct answer is option D (Red Pine distribution will shift northward into Canada)
Explanation:
Forest tree species are expected to endure significant population changes
in response to warmer temperatures across the United States.Red pine forests are negatively impacted by extreme summer heat, especially those
that have not been thinned. Red Pine species can be adapted to a wider range of climate, several subtropical and tropical pines, have a high degree of genetic variation and tolerate a wide range of climates. Performance in multi-site provenance trials shows that they are adapted well to a wide range of climates Thus they may also be able to adapt to new climatic conditions in their natural habitat.
Their are other factors which also influence red pine occurrence like soil conditions, plant competition. These factors are likely to be additional constraints for the present species distribution and future distribution shifts.
From these factors it is found that Red pine distribution will shift northward into Canada over the next 200 years.
Since there isn't suggested answers I'll answer you which are not found.
In mid latitude regions of the Earth the climate types that are lacking are the tropical climate types, and the polar climate types. The tropical climate types are concentrated around the Equator and in lower latitudes, while the polar climate types are concentrated around the poles and higher latitudes.

These include changes from year to year in water availability, potential damage to infrastructure, threats to biodiversity and ecosystems, impacts on agriculture and food security, higher energy consumption, and health impacts. The urban poor are likely to be the most at risk.
