    A 90 Correct Answer Incorrect Answer
    B 100 Correct Answer Incorrect Answer
    C 110 Correct Answer Incorrect Answer
    D 120 Correct Answer Incorrect Answer

    Solution

    (x – 1/x)2 = 3 => (x2 + 1/x2) – 2 = 3 (x2 + 1/x2) = 5 ∵ and we know that if (x + 1/x) = a then (x3 + 1/x3) = a3 – 3a => (x2 + 1/x2) = 5 => (x6 + 1/x6) = (5)3 – 3 × 5 = 110
