    Correct option is A

    Given:
    Digits: 2, 3, 4, 0, 5.
    Concept Used:
    To form the smallest five-digit number, the digits must be arranged in increasing order, keeping in mind that the number cannot start with 0.
    Solution:
    Arranging  the digits in ascending order: 0, 2, 3, 4, 5.
    The number cannot start with 0, so we must place the smallest non-zero digit at the start.
