[不定项选择题]资料：In a survey,people were asked to choose between treatments to save 600 people from dying a disease. Participants,including physicians,were asked to choose between a certain outcome that 200 people will be saved and a risky choice where there is a one-third probability that 600 people will be saved and a two-thirds probability that no people will be saved. In a second example,the group were asked to choose between allowing 400 people to die or a one-third probably that nobody will die and two-thirds probability that 600 people will die. In both examples,the first choices have an identical outcome as do their second alternatives.But faced with such a grave choice people did not spot the similarities. In the first example people opted to save 200 people over the gamble of losing people and in the second example people preferred the gamble over the certain outcome of killing 400 people. What the experiment shows is that wording can have potentially dangerous consequences.Most of people tend to feel losses much more strongly than the pleasure of making a comparable gain. In the second example，more people choose the option（ ）？
A.with a one-third probability that nobody will die
B.with a two-thirds probability that nobody will be saved
C.allowing 400 people to die
D.that 200 people will be saved
