Suppose a program has the following array declared in the data segment: array DWORD 99, 33, 77, 11, 22

And the program is supposed to reverse the array. After the program is finished, the array should be:

[22, 11, 77, 33, 99]

Which of the options below is the correct implementation of the program?

a.
mov ax, array
xchg ax, [array+4]
mov array, ax

mov ax, [array+12]
xchg ax, [array+16]
mov [array+12], ax

b.
mov ax, array
xchg ax, [array+16]
mov array, ax

mov ax, [array+4]
xchg ax, [array+12]
mov [array+4], ax

c.
mov ax, array
xchg ax, [array+8]
mov array, ax

mov ax, [array+2]
xchg ax, [array+6]
mov [array+2], ax

d.
mov ax, array
xchg ax, [array+2]
mov array, ax

mov ax, [array+6]
xchg ax, [array+8]
mov [array+6], ax
