The statement regarding arrays in C that is correct is that the memory address of an array remains constant.

In C, when you declare an array, the compiler allocates a block of memory large enough to hold all the elements of the array, and the location of that block is represented by the array's name, which acts as a pointer to the first element. This memory address does not change throughout the life of the array. Once an array is declared, its memory is reserved, and unless explicitly deallocated (in the case of dynamic memory allocation with pointers), that address will remain fixed.

This characteristic is essential in C, as it enables efficient access to array elements using indexing. It also allows for predictability when passing arrays to functions, as the function operates on the same allocated memory throughout its execution.

The other statements about arrays in C are inaccurate for the following reasons:

- An array's size cannot be changed after declaration. If a fixed-size array is declared, its size is immutable during runtime.

- Arrays in C can only hold elements of a single data type. If you need to store different data types together, you would typically use a struct or unions.

- Arrays do not have to be initialized at runtime; they can be initialized
