The correct answer is C. Millionaire.
The word "millionaire" is derived from the Latin words "mille" meaning "thousand" and "aere" meaning "silver". It is a noun that refers to a person who has a million or more units of a particular currency.
The word "millionaire" is first attested in the early 18th century. It became more common in the 19th century, as the Industrial Revolution led to the accumulation of great wealth by a small number of people.
The word "millionaire" is often used in a derogatory way to refer to someone who is wealthy but also greedy or selfish. However, it can also be used in a positive way to refer to someone who has achieved great success.
The other options are incorrect because they are not the correct spelling of the word "millionaire".
