Answer:
The best thing for them to do is to cooperate.
Step-by-step explanation:
In the Prisoner's dilemma game, cooperation would mean that the both parties are giving equal share of an amount. However, if they betray each other, the amount of money that will be given will be smaller, and if one betray the other, and the other remains silence, only one person will be rewarded. Hence cooperation is always the best option with the greatest reward in the Prisoner's dilemma game.
