In the Experiment Performed by De Martino, Kumaran, Seymour

In the experiment performed by De Martino, Kumaran, Seymour, & Dolan, participants were given $50 and were asked whether they would gamble on an all-or-nothing bet, or just keep $20 of the $50 they were given. The only difference between two groups was the framing of that question. What was the outcome?

A) Those who chose between the all-or-nothing bet and "keeping $20" chose to bet, whereas those who chose between the all-or-nothing bet and "losing $30" chose to lose the $30.
B) Both groups chose to go for the all-or-nothing bet.
C) Both groups chose to take the sure thing, even though it was framed as a gain for one group and a loss for the other group.
D) Those who chose between the all-or-nothing bet and "keeping $20" chose to keep the $20, whereas those who chose between the all-or-nothing bet and "losing $30" chose to bet.
