Answer:
Rikki-tikki, because he solves the problem
Explanation:
Rikki-Tikki-Tavi is a short story, from Rudyard Kipling's "The Jungle Book" about a mongoose, a pet to an English family, who successfully defended them from cobras.
In order to answer this question, we first need to define what does the term "protagonist" mean. Protagonist or the main character is usually the character around whose actions the story revolves and whose actions drive and develop the story. Also, the protagonist usually exhibits a set of values and virtues making the audience cheering for him. Sometimes, the term "protagonist" is equalized to the term "hero".
So, best fitting to this description is a brave mongoose, who riskied his own life to stop cobras from atacking his family thus saving the day.
