Answer:
The correct answer is "Someone has buried [the corpse] and disappeared"
Step-by-step explanation:
Dramatic irony is defined as a literary device in which the audience of a play knows something that the characters do not know. In the particular sentences provided the one that could be considered as a dramatic irony creator is "Someone has buried [the corpse] and disappeared" since the character who is expressing the disappearance of the corpse does not know what happened but the reader (or audience)does.
