Consider the following assembly code fragment: pushl %ebp movl %esp, %ebp subl $ emptyset x 40, %esp movl %ebx, emptyset x 14(%esp) movl $1, %ebx Which one of the choices is able to undo the effects of the fragment above? popl %ebp movl %ebp, %esp addl $ emptyset x 4 emptyset, %esp movl emptyset x 14(%esp), %ebx movl 14(%esp), %ebx addl $4 emptyset, %esp movl %ebp, %esp popl %ebp movl emptyset x 14(%esp), %ebx movl %ebp, %esp popl %ebp popl %ebp movl %ebp, %esp movl -emptyset x 26(%ebp), %ebx addl $emptyset x4 emptyset, %esp movl - emptyset x 26(%ebp), %ebx addl $ emptyset x4 emptyset, %esp movl %ebp, %esp popl %ebp
