Consider the operation PUSH AX :

Prior to execution of the instruction PUSH AX : the value of some of the relevant registers are AX $=$ B$3$C$5$ H$,$ SS $=13$C$5$ H $,$ SP $=$ A$43$B H

What is the correct value of these registers after the execution of the instruction PUSH AX $?$

AX $=$ B$3$C$5$ H$,$ SS $=13$C$5$ H $,$ SP $=$ A$43$D H

None given here

AX $=$ B$3$C$5$ H$,$ SS $=13$C$5$ H $,$ SP $=$ A$439$ H

AX $=$ Unknown, SS $=13$C$5$ H $,$ SP $=$ A$43$D H
