I am not really sure about the context of this question, but I believe the best answer would be C.
The first choice seems to symbolize elements that are not really true American heritage but rather cultural.
The second choice, I believe, pertains more towards having fun. However, one can stretch the meaning giving modern events to represent a facet of American culture (guns) but it doesn't really represent heritage.
The last choice seems to also have a playful tone regarding the Lone Ranger. In specifics, however, the Lone Ranger and Wild West is not really representative of neither the entire American culture nor American heritage.
That's why I believe choice C, or "grandmother knits the names...", is the best option to choose.
I'd say a comparative analysis because you are comparing how the two texts are similar. You can also include how they differ as well
He was saying that despite being a famous Army Officer, General Corrigan was a man who never forgot where he came or the people he grew up with. Despite his honors and rank, he was still same kid the narrator knew from many years ago. That fact that he greeted him with such enthusiasm tells a lot about the man behind the rank.
