    Explanation:

    The function floor () is used to give the integer which is smaller than or equal to the provided decimal value.

    for example:

    let a=5.8

    floor (a);

    the function provides the value 5 (smaller than or equal to 5.8).

    In the given code:

    variable num assigns the number 3.14.

    then, floor (3.14) gives the value 3 (smaller than or equal to 3.14).

    then, the echo print the value on the screen.

    Therefore, the correct answer is 3.
