For some reason, A and B are now faced with the choice between A and B. If they both choose plan A, they each get 3 units of benefits. If one person chooses Plan A and the other chooses Plan B, the person who chooses Plan A gets 8 units of benefit and the person who chooses Plan B gets 1 unit of benefit; If both choose plan B, they get 5 units each. It is assumed that both party A and Party B calculate and act in accordance with the standard of maximizing their own interests and understand the above situation of benefit gains and losses. They choose in no particular order and cannot exchange information during the choice, so they have only one choice opportunity.
Which of the following options can be derived?
A chooses plan A; B chooses Plan A
