The answer is D: After some soul-searching and introspection, Peter knew that it was time for him to move on.
Introspection is the action of self-reflection, that is to say, internal observation of one´s own state of mind. This kind of intra-personal observation can yield insights about one´s own corporeal, sensitive, cognitive and emotional states. It is contrasted to external observation of objects as different and external to the mind.  
 
        
             
        
        
        
In the very, very simplest terms, judging the validity of an argument starts centers around this process:
1) Identify the rhetoric (Lines of Argument) from the actual, formal reasons. Separate the persuasive language from the actual claims to truth and fact.
2) Analyze those reasons (claims to truth and fact) by identifying their logic (often in the Implicit Reasons) and evidence.
3) Test and evaluate the logic and evidence; identify logical errors and ask whether the evidence can and has been tested and objectively, repeatedly, factually verified.

Answer:
Point of view will show you the character's thoughts and feelings whereas voice shows the author's thoughts and feelings.
Explanation:
Point of view(POV): In a story, this is who is speaking. By "who is speaking" I mean, who is telling the story. There are multiple types of POV. Such as, First person (I or me), Second person (He or She), and Third person (They or Them). Though there are other points of view, these are the most common.
Voice: In a story, the author is also leaving clues as to how <em>they </em>feel about the situations. The other can use words with positive or negative connotations to show you. For example, "The murky body of water" vs. "The clear, sparkling ocean".
