Answer:
The answer is "4"
Explanation:
The two-dimensional array or 2D array is the simplest form of the multilateral array. This array can be written as a table, in forms of rows and columns. It also known as an array chart.
declaration of two-dimensional array:
Dim a(,) As Integer = {{4, 0}, {0, 4}, {0, 4}, {4, 0}}//declaring of multi-dimensional array
In the given 2D array code, there we need 4-row index value, as we known array indexing always starts with 0, and in this array, 5 rows is equal to 0 to 4, that's why 4-row index value is the correct answer.
