In which one of the following soils is saffron grown?

Saffron is grown in Karewa soil, which is mainly found in the Kashmir Valley of India. Karewa soils are lacustrine deposits formed from ancient lake beds and are rich in nutrients. They have a loamy texture, good drainage, and moderate moisture retention, which are essential for saffron cultivation. Saffron requires dry conditions during flowering and does not tolerate waterlogging, making Karewa soils ideal. The slightly alkaline nature of these soils also supports healthy growth of saffron corms. Due to these favorable physical and chemical properties, Karewa soil is best suited for saffron farming.
