The correct answer is Option 2.

• Cultivable Wasteland (Reh) is the land in which crops were raised for some period of time but has not been cultivated for the last five years due to certain deficiencies like alkalinity and salinity in the soils.
• Reh is infertile fine sand-like soil that is white in colour.
• It is basic in nature.
• Reh doesn't hold water but extensive use of fertilizers and irrigation can support paddy farming.
• Cultivable wastes are locally known as reh, bhur, usar, and Khola in some parts of North India.
• Rajasthan has a very high share of cultivable wasteland in total land use.

• The total land area on which crops are grown in a region is called the net sown area. 
• The net sown area and the area sown more than once together are called a gross cultivated area.
• The net sown area, current fallow, land under tree crops, and groves are included in agricultural land use.  
• The agricultural land in India is a little more than 50 per cent of the total geographical area in the country.
