Doodle is best symbolized by the bird, the scarlet ibis, because both are fragile creatures who struggle in their environments before dying tragic deaths.

To determine the best answer choice, we should analyze the text and find evidence from the story "The Scarlet Ibis." The story is about a young boy named Doodle who is born with disabilities and struggles to fit into the world. The scarlet ibis is introduced in the story as a bird that is not native to the area and is found weak and dying in the family's backyard.

Option 1: "Both are rare and unusual creatures who are tragically separated from their families."
While both Doodle and the scarlet ibis are unusual creatures and experience separation, there isn't explicit evidence that the scarlet ibis is separated from its family. It is more explicitly connected to Doodle and his family.

Option 2: "Both are fragile creatures who struggle in their environments before dying tragic deaths."
This seems to be the most accurate answer choice. Throughout the story, Doodle is depicted as fragile and struggling, just like the scarlet ibis. Both face challenges in their environments. The scarlet ibis eventually dies, and Doodle's tragic death is foreshadowed throughout the story.

Option 3: "Doodle loved rare and unusual birds that he felt were similar to him in a variety of ways."
While Doodle does express a fondness for birds, there isn't strong evidence to support that he specifically loves rare and unusual birds. The focus is more on his connection with the scarlet ibis.

Option 4: "Doodle saved the fragile bird, much as his brother attempted to save him when he was young."
This answer choice is partially correct. Doodle does save the bird by sheltering it from the storm, but it is not entirely accurate to say that his brother attempted to save him. Doodle's brother pushes him to overcome his disabilities and fit in with a harsh intent, which inadvertently leads to Doodle's downfall.

Based on the analysis, the most appropriate answer choice is:
Option 2: "Both are fragile creatures who struggle in their environments before dying tragic deaths."
