A Correct answer
Explanation

A 2-dimensional array requires exactly 2 indices - one for the row and one for the column. Each index specifies a position along one of the dimensions. Option D is incorrect because 2D arrays definitely need indices; option B (1 index) is for 1D arrays, and option C (3 indices) would be for 3D arrays.
