Answer:

To find the content of the stack and the stack pointer after the execution of each instruction, we'll start with the initial values and simulate each instruction step by step.

Initial values:

SP $($Stack Pointer$)=$ FF$2$EH

AX $=3291$H

BX $=$ F$43$CH

CX $=09$H

$1.$ PUSH AX:

Push the value of AX onto the stack.

The stack grows downward, so the SP will decrement by $2($since AX is $16$ bits or $2$ bytes$).$

Stack after PUSH AX:

Memory location at FF$2$CH: $3291$H

SP $=$ FF$2$CH

$2.$ PUSH BX:

Push the value of BX onto the stack.

Again, the stack grows downward, so the SP will decrement by $2($since BX is $16$ bits or $2$ bytes$).$

Stack after PUSH BX:

Memory location at FF$2$AH: F$43$CH

Memory location at FF$2$CH: $3291$H

SP $=$ FF$2$AH

$3.$ PUSH CX:

Push the value of CX onto the stack.

Once again, the stack grows downward, so the SP will decrement by $2($since CX is $16$ bits or $2$ bytes$).$

Stack after PUSH CX:

Memory location at FF$28$H: $09$H

Memory location at FF$2$AH: F$43$CH

Memory location at
