Answer:
3. The author includes details about his hard work to solicit sympathy for his situation.
Step-by-step explanation:
In his letter to the seller's website, Tyler remarks how he had eagerly waited to get his hands on the new Neutron Divider game. He also reveals how it had taken him a great deal of sacrifice and hard work to get a new copy instead of the cheaper used copy.
And in including how he had saved up to get the new CD, he is trying to solicit sympathy from the sellers to try to understand the trouble he had to go through to get enough money. The personal remarks might help his case, in the hope that the sellers will see the zeal he had and the hard work he had done in saving up money to get the CD.
Thus, the correct answer is option 3.
