Answer:
3. He knows that they cannot move the boulder blocking the doorway.
Explanation:
When the Cyclops attacks Odysseus and his men, Odysseus' first impulse is to attack and kill him to ensure the group's survival. However, they were inside the Cyclops' cave that closed the exit with a very heavy stone, impossible to be removed by humans. Only the Cyclops would be able to open that "door" and if Odysseus killed him, he and his crew would be trapped forever.
When Kindred and Cousin desert him, Everyman is sad but resolute.
He does not weep as he did earlier. Instead, he realizes that people make promises but do not intend to keep them. People offer "fair words" but not actions.
With this in mind, he resolves not to depend on other people but calls instead on his Goods. He thinks Goods will help him because there is power in money. He believes Goods will be more reliable than people. He says specifically that "money maketh all right."
Of course, material things will not be able to help him either. Goods even goes so far to tell Everyman that his focus on material goods has made things worse for him.
