Question

Please answer with explanation... I was told my answer is not fully correct when selecting the 1st, third, and 4th option

Suppose A and B are nonvoid, bounded, disjoint subsets of R. Mark all
of the properties that must be true.
sup(AUB) = max(sup A, sup B)
sup(A) + sup B
sup(AUB) > inf(AUB)
sup(AUB) > min(sup A, sup B)
□ If sup(AUB) & A, then sup(AUB) = B.
