According to the passage given above, deforestation and denudation will ultimately lead to which of the following?

1. Depletion of soil resource — Correct. Deforestation removes vegetative cover, causing erosion and loss of fertile topsoil; denudation directly degrades soil.

2. Shortage of land for the common man — Incorrect. This is not a direct or necessary consequence of deforestation/denudation in the usual environmental sense.

3. Lack of water for cultivation — Correct. Forest loss reduces infiltration and groundwater recharge, increases runoff, and can ultimately reduce water availability for agriculture.

So, 1 and 3 only are correct.
