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.
The first one is B because it is just stating the facts
A research paper is fact and nothing but the fact. A research paper is just giving information about a topic. However, rhetorical questions are used to persuade the reader to believe or agree with something, mainly in a discursive essay; but in a research paper, you aren't persuading, you are educating.
In "Do Not Go Gentle into That Good Night", Dylan Thomas' phrase "wild men" describes those who celebrate life.
