Hey there!
Your correct answer is option C.
Betty's grandfather was a hardy young man who traveled alone on a ship from Ireland to the United States. Although he worked years for meager wages, he eventually saved up enough money to buy a farm and start a family.
Notice that the word "meager" means to not have great quality, and the end of the sentence mentions eventually earning money to start buying a farm.
This tells us that Betty's grandfather was not very wealthy.
