Answer:
B. The temperatures are too high
Explanation:
First of all, a desert is a region with extremes of temperatures and little to no rainfall.
Organic matter is the remains of organisms that have died. They are an essential component of soils.
Where temperatures are very extreme, there would be little to no life. Only specialized organisms that have evolved to adapt will survive such a region.
Due to the fewer plants and animals' lives owing to the high temperature of deserts, little to no organic matter forms.
