For the Past Four Afternoons Sheila and Rachel Have Acted

For the past four afternoons Sheila and Rachel have acted out the same scene with their dolls: The girls put their dolls to bed. The dolls want the light left on. The girls tell the dolls that the light must be turned off at night. The girls then explain at length that the dolls will be safe in bed with the light off. The scene ends with the dolls going to sleep in the "dark" room. Such fantasy play is apt to:

A) Have little effect on the girls' fear of the dark
B) Help the girls constructively work through their own fear of the dark
C) Intensify the girls' own fear of the dark by focusing their attention on it
D) Enable the girls to deny their own fear of the dark by projecting it onto the dolls
