Answer is C.
Temperate deciduous forests is the biome which are dominated by climax communities of deciduous trees. These trees lose their leaves every autumn. These forests are also called as broad-leaf forests because the trees have wide, flat leaves. These biomes are exposed to warm and cold air masses, causing them to have four seasons: winter, spring, summer and fall. As winter approaches and daylight decreases, the production of chlorophyll in the leaves slows and eventually stops, revealing the bright red, yellow and orange colors we associate with fall.
