The correct answer to this is:
The Cyclops is compared to a mast, or flagpole, because of his size.
The similie suggests that even Cyclops is laying down he is still huge and looks like a mast among the sheep.
In the excerpt from Part 2 of the Odyssey, Cyclops is not compared to Zeus, rather the men are "lifting hands to Zeus" (praying) because they are being eaten and need help from Gods.
Also, Cyclops does not surrender, he is taking a nap as he is full after his meal.
