The soil type best suited for rice cultivation in Punjab is:

Sandy loam
Clayey loam
Loamy sand
Silt loam

The correct answer is: b) Clayey loam

Clayey loam is the best soil type for rice cultivation in Punjab because it has the right balance of sand, silt, and clay. Sand provides drainage, silt provides nutrients, and clay helps to retain moisture.

Sandy loam is a good soil type for rice cultivation, but it does not have as much clay as clayey loam. This means that it does not retain moisture as well, and rice plants may not get enough water.

Loamy sand is a good soil type for rice cultivation, but it does not have as much silt or clay as clayey loam. This means that it does not have as many nutrients, and rice plants may not grow as well.

Silt loam is a good soil type for rice cultivation, but it does not have as much sand or clay as clayey loam. This means that it does not drain as well, and rice plants may not get enough oxygen.

In conclusion, clayey loam is the best soil type for rice cultivation in Punjab because it has the right balance of sand, silt, and clay.
