A) Afforestation
B) Cutting the forests
C) Filling the land
D) Removing the topsoil

Answer 1

Hint:Flood is a natural calamity that comes after there is a lot of rain. One can analyze the given option and see if there is any method for the prevention of floods. One can elaborate on the methods given so as to provide the reason behind prevention.

Complete step by step answer:
1) First of all, we will learn some information about the floods. The flood happens due to the overflow of water on land which destroys anything that comes into its way. Floods are classified as a natural calamity that happens due to the over pouring of rain.
2) Now let's discuss the given options and see which can be a prevention for the foods. Option A states that afforestation can prevent floods. The afforestation means planting trees on land which are planted in a very large area. This planting of plants on a large area gives a land a specific grip and they can not be affected by floods. Also, the forests create resistance to the flood water which can prevent harm by the floods. Therefore, this option is the correct choice.
3) option B states that cutting the forest will prevent the floods. As we have discussed above the benefits of afforestation for the prevention of floods, we are now sure that cutting the forest won't help in the prevention of floods. Hence, this option is incorrect.
4) option C states that filing the land will prevent floods. Filling land with new clay material will not help as the land won't have much firmness due to the additional one new clay material. Hence, this option is incorrect.
5) option C states removing the topsoil will prevent floods and this option is incorrect as it won't have any effect on floods.
Therefore, option A is the correct choice.

Note: Floods are a natural disaster which causes very much destruction to nature. As it is mainly due to the over pouring of rainwater but there are many man made reasons which have made this disaster bigger. Planting trees will make the rain cycle stabilized and so there will be very few cases of such disaster.
