PLEASE HELP

Question: What is the most likely reason why the movie director left out this part of the novel?

Novel: There was an old door in this playground, on which the boys had a custom of carving their names. It was completely covered with such inscriptions. In my dread of the end of the vacation and their coming back, I could not read a boy's name, without inquiring in what tone and with what emphasis HE would read, 'Take care of him. He bites.' There was one boy - a certain J. Steerforth - who cut his name very deep and very often, who, I conceived, would read it in a rather strong voice, and afterwards pull my hair. There was another boy, one Tommy Traddles, who I dreaded would make game of it, and pretend to be dreadfully frightened of me.

Answer Choices:
a. because cutting this part helped limit the movie to a reasonable length.
b. because David's fears were not important to the story.
c. because there was no action or dialogue in this part.
d. because it would not be possible to show on film what David was imagining.
