    Answer: (2) 4 km/h
    Explanation:-
    A person goes from one point to another point with a speed = 5 km/h
    And comes   back to starting point with a speed  =  3 km/h

    Then, the average speed = (5 + 3 ) /2
    = 8/2
    = 4 km/hr
    Then, the average of a person is 4 km/h.

    Hence, the answer is (2) 4 km/h.
