Appalachian: A. Two continents colliding.
The Appalachian mountain range is an ancient example of a collision between two continental plates. Both plates have low density and little subduction occurs between them.
North American Cordillera: B. Terrane accretion
These form when two continents that collided bonded so tight that it forms a permanent land mass. If the continents would pull away from each other, the terrane stays intact.
Aleutian plate: D. Oceanic convergence
This is a type of convergence where one plate subducts beneath another plate. Between the two, the older plate is usually the one that subducts because it is usually more dense.
Andes mountain range: C. An oceanic plate and continental plate colliding.
In the collision between an oceanic and continental plate, the thinner and more dense oceanic plate subducts under the continental plate. The Andes mountain range was formed by the subduction of the Nazca Plate beneath the South american Plate.

Answer: Option B
Explanation:
Deforestation can be defined as the cutting down of trees in huge number. This act increases the amount of green house gases in the environment.
This is so because the carbon dioxide which is an important green house gas is absorbed by the trees which reduces the concentration of green house gas and thus decreases green house effect.
But lesser number of plants will increase the amount of carbon dioxide in the atmosphere thus increasing the green house effect.
