According to Ministry of Water Resources, waterlogged areas are the land areas having

Correct option is A

The correct answer is (A) Water-table within 2 m from land surface

Explanation:
• Waterlogging is a condition of the land where the soil profile is saturated with water, either permanently or periodically, to the extent that it restricts the normal aeration of the soil.
• The Ministry of Water Resources (India) has defined waterlogging based on the depth of the water table.
• Waterlogged: Water table is within $2.0 meters$ of the ground surface.
• Potentially Waterlogged: Water table is between $2.0$ and $3.0 meters$ from the surface.
• Safe: Water table is below $3.0 meters$ from the surface.

Information Booster:
• Waterlogging leads to anaerobic (oxygen-free) conditions, which causes the accumulation of toxic substances and harms root respiration.
• It is often caused by over-irrigation in canal commands, poor drainage, or seepage from unlined canals.
• Salinization often accompanies waterlogging because the high water table allows salts to move to the surface via capillary action.

Additional Knowledge:
• Standing water (Option D) is a visible form of waterlogging but is not the technical limit for defining the condition of the soil profile.
• Reclamation of waterlogged soils usually involves installing surface or sub-surface drainage systems to lower the water table.
