Explanation: Lets take a two-dimensional array alphabet[4][4]
Lets say this array contains the following elements: Example 1
a b c d
l i o n
f e l l
s t e m
These are the strings with same length. So this 2D array can contain strings of same length.
Now lets take another 2D array Example 2
a b c
h i n t
s o
e g g
2D array can have all these above mentioned elements. So it can contain strings of different lengths.
Now consider the Example 2. Some places for the elements are left. This isn't an issue for 2D array. So it can contain uninitialized elements too.
So the answer is All of above.
