Answer:
Elijah is in the pre-operational stage.
Explanation:
The pre-operational stage is from ages 2-7. It is characterized by children being able to think based on symbols, and they are not yet able to think logically. They could not process yet how events can be changing. One feature of this stage is centration, which is the ability to focus on only a single phase of an event at a given time. This is what is shown in the example. Elijah can only process that his peas and carrots can be eaten if they are together, and he thinks that they are not to be eaten if spread out.
