    (1/p).
    A 138 Correct Answer Incorrect Answer
    B 140 Correct Answer Incorrect Answer
    C 142 Correct Answer Incorrect Answer
    D 144 Correct Answer Incorrect Answer

    Solution

    Given, √p + (1/√p) = 12
    On squaring both the sides,
    So, p + (1/p) + 2 × √p × (1/√p) = 144
    Or, p + (1/p) + 2 = 144
    So, p + (1/p) = 142
