      A.
      A √746 Correct Answer Incorrect Answer
      B √740 Correct Answer Incorrect Answer
      C √750 Correct Answer Incorrect Answer
      D √730 Correct Answer Incorrect Answer

      Solution

      Maximum value of a sin A + b cos A = √(a² + b²)
      Here, a = 25 and b = 11
      Required value = √(25² + 11²) = √(625 + 121) = √746
