Answer:
B. The drooping feather
Step-by-step explanation:
From the excerpt above, the symbolism of the drooping feather is such that it is not a common sight to see someone put it on a crown without a special reason or need to do so and it is meant to send a particular message to anyone that sees it.
So, we can infer that is in fact the symbol of the grandpa's heritage in this excerpt because it symbolizes heritage.
