Which of the following code fragments will successfully initialize a two-dimensional array of chars named cA with a size such that cA[2][3] refers to a valid element?

1. char[][] cA = { { 'a', 'b', 'c' }, { 'a', 'b', 'c' } };

2. char cA[][] = new char[3][];

       for (int i=0; i<cA.length; i++) cA[i] = new char[4];

3.char cA[][] = { new char[ ]{ 'a', 'b', 'c' } , new char[ ]{   'a', 'b', 'c' } };

4char cA[3][2] = new char[][] { { 'a', 'b', 'c' }, { 'a', 'b','c' } };
