A Correct answer
Explanation

A 2-dimensional array requires exactly 2 indices to reference an element: one for the row and one for the column (e.g., array(1,2)). Option B is incorrect because one index only works for 1D arrays. Option C is incorrect as 2D arrays don't use 3 indices. Option D is incorrect because all arrays require indices for element access.
