Answer:
The author's intention in describing how Monsieur Loisel planned to spend his savings is to show that he is frugal and faithfully saves for something he wants.
Step-by-step explanation:
Option A fits the author's intention because of the following reasons.
1. At the beginning of the excerpt, the author pointers out that Monsieur Loisel got slightly pale and he was making savings to purchase a gun; This can be summarised as being frugal (sparing or economical as regards money or food). Being pale, as used in this excerpt is as a result of depriving himself of good food.
2. The author also pointed out that he planned to shoot with some friends on a certain day; This illustrates his willingness to buy whatever he wants.
