B Correct answer
Explanation

In Java, arrays must be declared with brackets after the type or variable name, not C-style syntax. Line 3 uses correct syntax int[][] a1 = new int[3][3]. Line 4 attempts C-style declaration int a2[4] which is invalid. Line 5 declares int a2[5] without initialization using C-style which is also invalid.
