    The distance between the points \[\left( \mathbf{x},\mathbf{0} \right)\] and \[\left( \mathbf{0},\mathbf{y} \right)\] is

    A)  \[{{x}^{2}}+{{y}^{2}}\]                 

    B)  \[x+y\]           

    C)  \[{{x}^{2}}-{{y}^{2}}\]                   

    D)  \[\sqrt{{{x}^{2}}+{{y}^{2}}}\]

    Correct Answer: D

    Solution :

    (d): \[\sqrt{{{(x-0)}^{2}}{{\left( 0-y \right)}^{2}}}=\sqrt{{{x}^{2}}+{{y}^{2}}}\]
