Answer: D. The use of two exclamation points.
Step-by-step explanation:
"A Red, Red Rose", a poem by Robert Burns, is about a speaker who describes his love for his partner, comparing her to a red rose. The speaker informs her that he must leave and bids farewell to her, but insists that he will come back:
"And fare thee weel, my only luve! And fare thee weel a-while!"
In these lines, the poet uses exclamation points to further emphasize his words. The speaker wants to convince his loved one that he will come back, and shows his desire to reunite with her.
