Size of the dimensions is required to specified only at the time of instantiation and not at the time of declaration. For example, int[][] ia; //this is a valid declaration. int[][] ia = new int[2][3];//this is a valid declaration and a valid instantiation.

Just a little suggestion in the example also int[][] ia=new int[3][] is also valid,

as the choice 3, sasy

The number of rows and columns must be specified at the time it is declared.

thank you for your feedback!

It seems that only the first dimension should be decalred in multidimensional array:
int [] [][]arr = new int[2][][];

but in choice 3 I read:
the last dimension can also be left out at the time of instantiation for an array of more than one dimension.

Thanks

You are right the explanation is incorrect. Fixed.
