Answer:
D). someone of high rank and influence.
Step-by-step explanation:
The word 'dignitary' stands for 'an important or influential person, or one of high rank or position.' In the given excerpt, the word 'dignitary' has been employed as a metaphor for 'death' and signifies its 'high rank' given to it by the military men. They treat it with uttermost silence and respect which is reflected through the captain's motionless state with 'folded arms.' Thus, option D is the correct answer.
