D
Forested mountains
Explanation: 

Detailed explanation-1: -It is a temperate desert with hot, dry summers and snowy winters. The valleys are dominated by sagebrush and shadescale. The biologic communities on the mountain ranges differ with elevation, and the individual ranges act as islands isolated by seas of desert vegetation.

Detailed explanation-2: -The Great Basin Desert exists because of the “rainshadow effect” created by the Sierra Nevada Mountains of eastern California. When prevailing winds from the Pacific Ocean rise to go over the Sierra, the air cools and loses most of its moisture as rain.

Detailed explanation-3: -Ans : The Great Basin Desert, located in the physiographic Great Basin that encompasses almost all of Nevada, western Utah, and parts of neighbouring states, is classified as a cold mid-latitude desert.

Detailed explanation-4: -The dominant native vegetation region-wide is sagebrush, especially big sagebrush. Other cold-temperate shrubs are shadscale saltbush and winterfat. Shrubs with evolutionary ties to warmer climates include rabbitbrush, blackbrush, and horsebrush. Other shrubs include greasewood and Nevada ephedra.
