    A 26 Correct Answer Incorrect Answer
    B -26 Correct Answer Incorrect Answer
    C 12 Correct Answer Incorrect Answer
    D 16 Correct Answer Incorrect Answer

    Solution

    If (u - 5) 2 + (v + 2) 2 + (w тАУ 4) 2 = 0, then (u = 5), (v = -2), and (w = 4).

    So,
    - u - 5 = 0 тЖТ u = 5
    - v + 2 = 0 тЖТ v = -2
    - w - 4 = 0 тЖТ w = 4

    Therefore, required value:
    4(5) - (-2) + 4 = 20 + 2 + 4 = 26
