Best Answer Explained in Below-:

The correct spelling of the word is "competition" (Option A). This term originates from the Latin word "competere," which means to strive together. "Competition" refers to the act of competing or contending with others for a prize, recognition, or superiority in various contexts, such as sports, academics, or business.

The incorrect options include various misspellings:

- **Option B: Competision** – This misspelling incorrectly uses an "s" instead of a "t," which alters the proper formation of the word.
- **Option C: Competetion** – The repetition of the "e" is unnecessary and violates the standard conventions of English spelling.
- **Option D: Compitition** – The use of "i" instead of the second "e" is incorrect, as it deviates from the established phonetic structure of the word.

Understanding how spelling is constructed from its roots and its phonetic structure can assist in avoiding these common pitfalls. Therefore, "competition" (A) is the only option that aligns with the correct spelling conventions of the English language.
