Usar soils are saline in character because of high salt content and poor drainage in semi-arid climates where evaporation concentrates salts. These soils often have a whitish or grayish surface and a salty or alkaline subsoil layer, reducing crop suitability without reclamation. Regur is black cotton soil rich in clays and moisture-retention but not inherently saline. Khadar refers to new Alluvial soils, usually fertile and not saline. Kari soils are shallow and may be stony or sandy, but salinity is not their defining feature. Thus, among the options, Usar is the one with pronounced salinity.

The correct option is A. The Kashmir Valley is widely recognized as the fruits and vegetables region. It is famous for high-value fruit crops such as apples, cherries, apricots, and walnuts, and also produces a variety of vegetables.
