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 ```
