    Answer: (c) 5 km
    Explanation:-

    A man walks in East direction = 1 km
    He walks in the South direction= 5 km
    Again he walks in east direction = 2 km
    After, he walks in the North direction = 9 km

    Given figure-

    In right angle triangle
    hypotonuse2 = base2 + perpendicular2     (by Pythagoras theorem)
    Therefore, DE2 = 42+ 32  = 16 + 9 = 25
    DE = 5 km
    Hence, the distance from starting point is 5 km.
