      (1/b).
      A 117 Correct Answer Incorrect Answer
      B 119 Correct Answer Incorrect Answer
      C 121 Correct Answer Incorrect Answer
      D 123 Correct Answer Incorrect Answer

      Solution

      Given, √b + (1/√b) = 11
      On squaring both the sides,
      So, b + (1/b) + 2 Γ— √b Γ— (1/√b) = 121
      Or, b + (1/b) + 2 = 121
      So, b + (1/b) = 119
