The correct answer is option d, that is, temperate forests.
Step-by-step explanation:
Temperate deciduous forests refer to the forests that show four different seasons. Leaves in these forests go through distinct kinds of adaptations on the basis of the season. The leaves modify color in autumn, get fall in winters and grow back in springs.
The cause of the modification in the color of the leaves is the fluctuation in season at the time of late autumn, in this season, the plants encounter with change in weather from summer to winter, that is, from hot to cold situations. The plants cease the procedure of photosynthesis as it needs water.
In order to inhibit water loss from photosynthesis and transpiration, the chlorophyll pigment found in the leaves gets dissociated into basic components. Due to complete dissociation of chlorophyll, the other pigments start to demonstrate their colors, thus, leaves show red or yellow color in autumn season.
