Suppose x and y are two array variables. What is the semantics in Tiger for the assignment

x :$=$ y

Question $1$Select one:

The elements of array y are copied one by one into array x$,$ so that the two arrays are allocated in different memory locations but contain the same elements.

The pointer to array y is copied into variable x$,$ so that now both x and y point to the same array on the heap.

Assigning entire arrays does not work in Tiger, it is necessary to copy individual array elements manually.
