Solution
The correct option is:
A
They are adapted to the cold environment.
The climate in hilly areas is colder and drier than in plain areas. Thus, the moister content of the air is less and trees need to conserve as much water as possible. They have needle-like leaves so that they do not lose much water by the process of transpiration. The tress present in hilly areas are tall so that they can get enough sunlight. All these adaptations are for the better survival of these plants.
