**Question:** Consider the poset ({2, 4, 5, 10, 20}, |). What are the upper bounds and lower bounds of {5, 10}?- ○ Upper bounds: 10, 20; Lower bounds: 2, 4, 5- ○ Upper bounds: 20; Lower bounds: 5- ○ Upper bounds: 10, 20; Lower bounds: 5- ○ Upper bounds: 20; Lower bounds: 2, 4The question is about finding upper and lower bounds in a partially ordered set (poset). A poset is defined here with the elements {2, 4, 5, 10, 20} and a relation, likely divisibility.The answer choices provide different sets of upper and lower bounds for the subset {5, 10} within this poset.
