  2. B.bush burning
  3. C.crop cultivation
  4. D.seasonal rainfall
  5. E.temperature
Show the answer and explanation

Explanation

Savanna's pattern is explained by seasonal rainfall and by human activities such as bush burning, grazing and farming, which turn forest into derived savanna. Temperature is high all over tropical Africa, so it does not explain the pattern.
