Answer:
defecating stage
Explanation:
According to my research on the Freudian theory of development, I can say that based on the information provided within the question Lena is most likely fixated with the defecating stage. In this stage early potty training can lead to the child becoming an defecating-retentive personality who hates mess, is obsessively tidy, punctual as well as overly controlling. Which are all the behaviors that Lena is demonstrating.
**Had to change the name of the Stage because brainly detects it as an innapropriate word, but the name of the stage is the bodily organ in charge of defecation**
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
