Answer:
This example shows that the three areas of development D. overlap and interact.
Step-by-step explanation:
As we can conclude from the situation described, baby Sanjay is not developing one area at a time. At the same time his motor skills are increasing, and because of that increase, he has experiences that improve his cognitive and social/emotional development. He experiences anger while having an object taken away from his hands, as was described, which is an overlap of areas - more than one thing taking place and being processed simultaneously.
