Lincoln's <em>Gettysburg Address</em> describes the bravery of Union soldiers where Lincoln speaks about the sacrifices of the soldiers and what it meant for the war during that time. He applies certain diction for the speech in order to make it more memorable.
In <em>Letter to His Son,</em> Robert Lee uses subjective style of writing because the author addresses to his own son and therefore the language is more personal. Like, Lincoln's speech, the letter also concerns the importance of the soldier's resistance for the fate of the Union.
The correct answer is D.
Demonstrating bravery huh? It doesn't seem too hard to explain. Say, for example your talking about a fictional story, right? Depending on what that said character does, depends on his/her bravery for he/she did. If you can implement something similar to that in whatever it was you had in mind, it might help.
I really hope this helps.
