Best Answer Explained in Below-:

The question "Which is the correct spelling?" presents several options that attempt to convey the word relating to how something is articulated. However, all the given options are misspellings of the intended term, which is "pronunciation."

The correct spelling, "pronunciation," is derived from the verb "pronounce," which means to articulate the sounds of a word correctly. The primary mistake in the options is the insertion of incorrect letters that do not align with standard English phonetics and spelling conventions.

For instance, "Pronounciation" (commonly misused) erroneously suggests a link to the word "pronoun," which is unrelated. The variations such as "Pronunciasion" and "Pronounciason" further stray from the root word "pronounce," introducing incorrect letter sequences.

In English spelling, understanding the root and its modifications is crucial. The ending "-tion" indicates a noun form derived from a verb. Therefore, the correct spelling "pronunciation" effectively captures the essence of the word's meaning without introducing confusion. In summary, the answer to the question regarding correct spelling should point to "pronunciation" rather than any of the provided options.
