Expert Solution

Step 1: Providing Introduction

According to our guidelines, we are allowed to solve only the first question. Please post the other question separately.

Register state must be preserved before a procedure is called in assembly language and low-level programming, and register values must be restored after the procedure. By doing this, it is ensured that the method can use these registers without having an impact on the surrounding code. This can be accomplished using a variety of operators or instructions. We shall assess the suitability of the following options in this situation: "USES", "PUSH", "PROC", and "SAVE."

Please refer to the following steps for the complete solution to the problem above.
