    B 840 Correct Answer Incorrect Answer
    C 900 Correct Answer Incorrect Answer
    D 600 Correct Answer Incorrect Answer

    Solution

    Ten-thousandth place cannot be 0. Because the number becomes four digit if the ten thousandth place is 0.

    Therefore, total possible numbers that can be formed = 5 X 5 X 4 X 3 X 2 = 600
