    1)?
    A 5 Correct Answer Incorrect Answer
    C 6 Correct Answer Incorrect Answer
    D 2 Correct Answer Incorrect Answer

    Solution

    ATQ;
    We know that (aᵐ + bᵐ) is divisible by (a + b) when m is an odd positive number.
    Here, m = 19, therefore (q¹⁹ + 1) is divisible by (q + 1).

    Therefore, the required remainder will be 0.
