    B. i only

    Read Explanation:

    • Settled agriculture is possible only where a permanent source of water is available.

    • Farmers have practised agriculture along the Nile valley in Egypt for more than 5000 years.

    • They devised a system of using floodwaters for irrigation by storing the overflow from the Nile in shallow basins that were bounded by raised banks.

    • This water could be stored for more than a month and was lifted into narrow canals with the help of water-lifting devices, such as the shaduf and the noria, that were powered by animals and human beings.

    • The canals directed the water to the fields where rice and cotton were grown in summer, and wheat, barley, beans and other crops were produced in winter.

    • Palm trees were also grown, and almost every part of these trees was used in one way or another.
