A large area of forest was destroyed completely by forest fire. Which of the following statements hold(s) true regarding it?

(i) More soil will be eroded as the soil is not protected by trees from wind and rain.
(ii) The land will have more fresh air as there are lesser trees to take in oxygen.
(iii) Wildlife will inhabit the cleared area because more space is available now.
(iv) New trees will grow quickly to replace the burnt ones as the ash of the burnt trees will make the soil more fertile.

A (i) only
B (i) and (iv) only
C (i), (ii) and (iv) only
