Question

You can reveal more about your character's feelings by ____

Answer 1

I would say B because through dialogue your character may express his or her feelings

Answer 2

You can reveal more about your character's feelings by using dialogues.

Dialogues give the writer the opportunity to show how each character reacts in different human interactions and social situations, the reader can see the feelings of a character emerge from the lines even when they don't explicitly say it, context plays a big part of what we communicate with stories.

Variyig your sentences can show a big range of vocabulary or structure but it doesn't necessarily show deeper details of the characters.

Borrowing from established literature imitates the develope of characters to previously planned material.

And repeating important action might emphasize details but not actually bring them to light.
