    option D

    eduncle-logo-app

    we know that metallic radii is greater than covalent radius and down the group size increase. so metallic radii of K will be greater than Na (x>p) and also covalent radii of K will be greater than Na ( y>q) so overall x > p,q,y

    39 option D

    eduncle-logo-app

    for 39 see reason... metal ions are touching the electrons and are not like overlapping which is the case of covalent radii. Because of this ,metallic radii of atoms is greater than the covalent radii of those metals..

    eduncle-logo-app

    down the group metallic radii increases... so the metallic radii of K is greater among all

    please mark the answer shib if it helps u😊🙏
