Answer:
3. Scarecrow.
2. The Wizard of Oz.
1. Toto.
Explanation:
Every relationship that Dorothy forms- both in the book and film- are important to her growth both as a character and a person in the real world. Try and put yourself in her shoes. You are living with your relatives when all of a sudden, a cyclone(or any natural event) whisks you away from them. How hard can that be? Forming new bonds and relationships can help to diminish some of that pain. I will explain why I think the bonds listed above are the most important:
1. Toto.
Toto is Dorothy's lovely companion throughout this entire tale. He sticks by her side, even as times get rough. This dog is just as humane as all of us combined, and he is one of the most important bonds that Dorothy will ever have.
2. The Wizard of Oz.
Even though his arc comes later than expected, this phony wizard is really nothing more than a sympathetic old man. He just wanted to feel accomplished, but he earned it through lies and shady practices. He is easy to understand, and even helps Dorothy return home. This is an influential bond that Dorothy has.
3. Scarecrow.
This man made of nothing but straw and more straw is one of the most humane protagonists to ever exist. His plight is easy to get: he wants to feel smart. Don't we all from time to time? His goal is simple: to go to the ruler of his land and ask for brains. Even though he is a bit naive, the Scarecrow man is much more intelligent than he appears. He is both important and influential to Dorothy.
Hopefully this helps you with your inquiry. I would advise reading the book to get your own opinion. Or watch the movie. It is a lovely adaptation.
