The tireless assistance of "workers" during funeral rituals is not only to show proper respect to the "owners," but also to:
A) guarantee that the "owners" will reciprocate the favor of "working" at a later funeral.
B) avoid suspicion of involvement in causing the death.
C) avoid mourning taboos and obligations by "paying their debt" as soon as possible.
D) protect themselves from the dead person's angry spirit, which remains around the corpse.
