The correct option is B.
The area described in the question given above is desert. Most plants in the desert either have small leaves or no leave at all, in order to regulate the amount of water that is lost to the atmosphere via evaporation of water from the leaves. Most deserts are found within the latitude 30 degree north and latitude  30 degree south. Some deserts can also be found around mountain. The temperate range in desert is quite wide. During the day, the temperature may be as high as 50 degree Celsius and the temperature may drop below zero degree Celsius in the night. Thus, it is always very cold at night compares to during the day.
        
             
        
        
        
Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell. 
CELL DIVISION:
- Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms. 
- According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.
- In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellular division.
