There are several possible reasons why a 2D array can have varying values when passed to a function:

1. The array may be of dynamic size and is not properly initialized before passing it to the function.

2. The function may be modifying the array elements inside the function, causing its values to change.

3. The function may have a bug or an error in its logic that causes unexpected behavior, including changes in the 2D array.

4. The 2D array may be a pointer/reference to a larger array or data structure, and the function is modifying the larger structure, which in turn affects the values of the 2D array.

5. The function may be using an incorrect indexing or addressing scheme for the 2D array, resulting in accessing incorrect or uninitialized values.
