While a child watches, you hid a cheerio under one of two cups in front of her. the first three times you hide it under the blue cup; the fourth time you hide it under the red cup. she still looks for the cheerio under the blue cup. this child has not yet fully comprehended:
a. accomodation.
b. object permanence.
c. difference in color.
d. assimilation.

Option A – Accomodation.

The child has not yet fully comprehended because she has not accommodated herself to learn a new process.  

Explanation:

As the child watches the Cheerio being hidden repetitively under the blue cup, the child looks for the Cheerios only under the blue cup even though it is changed and kept under the red cup. According to her, the new change of position is not accommodated. The child does not comprehend the new change in the practice.

Accommodation is a learning process where a child adapts and learns to pick new information by changing the previously existing ideas. Alteration of existing schema, idea, or a thought leads to learning a new experience.

Assimilating is learning a new idea by fitting it into an existing idea. The difference in color or object permanence does not matter because the child knows the red and blue colors as wells the Cheerios.
