Explanation:

In this scene, Lady Macbeth is trying to convince Macbeth to go through with the murder of Duncan. She is appealing to his courage and their shared ambition. The context of the play shows that Macbeth has doubts, and Lady Macbeth is using emotional persuasion (like challenging his courage with "screw your courage to the sticking - place") to get him to commit the act. The other options don't fit as well. Proving loyalties to the crown (when they are about to betray the king) is incorrect. Hiding true purpose is more about their overall plot, not specifically Macbeth's appeal. Deceiving the king and servants is part of the plan, but the main emotional appeal here is to get Macbeth to commit the murder.

Answer:

to convince his wife that he is prepared to commit the murder
