B; "The doctor tells the story from the first person point of view"
Explanation:
We automatically understand that it is not "A" or "D," as the final sentence states "said I," and the fourth paragraph states "Yes, Colonel, a great victory," indicating that he himself is referencing the Colonel. Finally, the first sentence talks about a first hand recount of a patient's condition; typically a doctor would say this. Therefore, the answer would be "B."

operations" that is a tool the Federal Reserve uses to influence the
volume of money in the economy by buying and selling government
securities. </span>
Surely it's D) Simile. It is a figure of speech that is used too compare two states or smth else. You can identify it by the words "like" and "as". The phrase means that there's a lot of dirt around us and it is a common thing to see that.
