The correct answer is C. The correct spelling of the word is “referendum”. A referendum is a direct vote by the electorate on a particular issue or proposal. The word comes from the Latin words “res”, meaning “thing”, and “ferre”, meaning “to carry”. The first recorded use of the word in English was in 1842.
The word “refrendum” is a misspelling of the word “referendum”. It is likely that the misspelling arose due to a misunderstanding of the Latin word “ferre”. The word “ferre” can also mean “to bear” or “to bring”. It is possible that someone who was unfamiliar with the word “referendum” mistook it for a word meaning “to bring a matter to a vote”.
The word “refrendum” is not a recognized word in the English language. It is not listed in any dictionaries and it is not used in any formal or informal writing. The word “referendum” is the only correct spelling of the word.
