The correct answer is: D. intElements = intNums.Length
The Length property of an array returns the number of elements in the array. In this case, the intNums array is a one-dimensional array, so the Length property will return the number of elements in the array.
The Len function is used to get the length of a string. It is not used to get the length of an array.
The intNums.Len property is a shortcut for the Length property. It is equivalent to intNums.Length.
The intNums.Length property is the preferred way to get the length of an array. It is more concise and easier to read.
