Final answer:
Aeschere's body is missing, making a funeral impossible.
Step-by-step explanation:
The reason they are unable to give Aeschere a proper funeral is because Aeschere's body is missing, making a funeral impossible. In the epic poem Beowulf, Aeschere is a warrior who is killed by the dragon. When Beowulf and his men go to confront the dragon, they discover that Aeschere's body has been taken by the dragon. Without a body, it is not possible to hold a proper funeral. So, option (a) is the correct answer.
