    The work done to lift the suitcase is 4 Joule.

    Option B is correct.

    Given:

    Height = 0.5 m

    Force = 8 N

    To find:

    Work done = ?

    Formula used:

    Work done is given by,

    W = f * s

    where f = force

    s = displacement

    Solution:

    Work done is given by,

    W = f * s

    where f = force

    s = displacement = height

    W = 8 * 0.5

    W = 4 Joule

    Thus the work done to lift the suitcase is 4 Joule.

    Option B is correct.
