    Answer:

    B. 1, 4

    Read Explanation:

    • In certain geological formations, water is available from artesian wells

    • Communities living in deserts have devised various innovative means of obtaining a per-manent supply of water.

    • The qanat or kariz is an example of an indig-enous system of transporting water common in South West Asia, especially Iran

    • In this system water is transported by gravity through underground tunnels from alluvial aquifers to an agricultural settlement.

    • The water thus brought to the villages is shared through a system of community management which ensures that the distribution is equitable and its use is sustainable.
