Answer:
D.
Step-by-step explanation:
Epic simile can be defined as an extended simile which runs over several verses in an epic poetry. It is also known as Homeric simile. This device is used to compare one action with the other action in epic poetry. In the epic of Beowulf, epic simile is used extensively.
When the poet describes the beam of wood that Beowulf has found, it can be compared picturized like the mast of an enormously large ship based on epic simile.
The lines from the epic 'And it was like a mast /a lugger of twenty oars, broad in the beam— /a deep-sea-going craft—might carry: /so long, so big around, it seemed.' suggests that the size of the beam is enormous as that of a ship.
Thus the correct option is D.
