    Solution:

    A) Z= 62....f-block
        Z=58 to 71 are lanthanoids.
    B) Z=47....d-block
        47- 18=29.We know Z=29 is copper
        So Z=47 belongs to copper group.
    C) Z=56....s-block
        56-18=38
        38-18=20
        So Z=56 belongs to "Ca" group.
    D) Z=53....p-block
        53-18=35
        35-18=17
        So Z=53 belongs to "Cl" group.
