Question

read the sentence.i told them how surprised and excited i was to have my painting selected, especially since i’d felt so incompetent at the beginning and i knew the competition was so ruthless.which revision best uses dialogue to improve the sentence?

Answer 1

Unfortunately, you didn't share any options so that my answer could coincide with your option list given with the task, but think we have got the same things. I am pretty sure that the revision which best used in dialogue to improve the sentence is:

“Did you hear?” I asked them. “My painting got selected! Exciting, right?” I smiled.
Hope it will help you in some measure.
