      GIVEN-
      √[41-√{21+√(19-√9)}]
      TO FIND-
      Solution to the given expression.
      SOLUTION-
      √[41-√{21+√(19-√9)}]
      = √[41-√{21+√(19-3)}]
      = √[41-√{21+√(16)}]
      = √[41-√{21+4}]
      = √[41-√{25}]
      = √[41-5]
      = √[36]
      = 6
      FINAL ANSWER-
      Option 'a' i.e. '6' is the correct answer to the given question.
