Assume that an integer array named intValues contains intNUM elements. Which of the following code segments most efficiently finds the largest element in the array and displays it in a label named lblMaxValue? Assume that values have already been inserted into the array.
A) For intIndex = 0 To intNUM - 1 If (intValues(intIndex) CInt(txtMax.Text)) Then
LblMaxValue.Text = intValues(intIndex).ToString
End If
Next intIndex
B) intMax = intValues(0) For intIndex = 1 to intValues.length - 1
If intValues(intIndex) intMax Then
IntMax = intValues(intIndex)
End If
Next
LblMaxValue.text = intMax.ToString
C) For intIndex = 0 To intNUM If intValues(intIndex) intMax Then
IntValues(intIndex) = intMax
End If
Next
LblMaxValue.Text = intMax.ToString
D) intMax = intValues(0) For intIndex = 1 To intValues.length
If intValues(intIndex) intMax) Then
IntMax = intValues(intIndex)
LblMaxValue.Text = intMax.ToString
End If
Next

Option B is the most efficient because it uses a simple loop to iterate through the array and store the maximum value in a separate variable (intMax). It then displays the max value in the label (lblMaxValue). The code in option A is incorrect as it should use intMax instead of txtMax. The code in option C is incorrect as it sets intValues(intIndex) to intMax, which does not make sense. The code in option D has an unnecessary if statement inside the loop, and it displays the max value inside the loop instead of displaying it after the loop finishes.
