    Answer:

    3 digits .

    Explanation:

    The least count of the ruler that is being used is 0.1 cm , hence it can measure upto one decimal point of cm . One more decimal point can be inferred .

    So the measurement of 5 cm will look like

    5 .00 cm or it will have 3 significant figure . The last figure of the measurement suffers from error as it has been inferred or guessed.
