when vegetables are cultivated by the size of the talking fan cities and that said to the market daily the process is called a. Shifting cultivation b. Truck farming c. Terrace cultivation d. Plantation farming

Dear Student,
The regions where farmers specialise in vegetables only or grow mainly vegetables, the farming is known as truck farming.Truck farming, horticultural practice of growing one or more vegetable crops on a large scale for shipment to distant markets. It is usually less intensive and diversified than market gardening. At first this type of farming depended entirely on local or regional markets.Hence option B is right.
