    Answer:
    c. 2520

    Explanation:
    Repetition is not allowed, therefore:
    1st digit can be any of the given 7 numbers
    2nd digit can be any of the remaining 6 numbers
    3rd digit can be any of the remaining 5 numbers
    4th digit can be any of the remaining 4 numbers
    5th digit can be any of the remaining 3 numbers
    This means that:
    number of possible combinations = 7 * 6 * 5 * 4 * 3 = 2520 numbers

    Hope this helps 🙂
