    A) 500 pm            

    B) 566 pm

    C) 600 pm                        

    D) 693 pm

    Correct Answer: D

    Solution :

    [d] Body diagonal [d] of a cubic crystal of edge length [a] is given by, \[d=a\sqrt{3}\] putting a = 400 pm, we get \[d=\sqrt{3}\times 400 pm = 692.8 pm\approx 693 pm.\]
