The correct answer is: D. Committee
The word "committee" is a noun that refers to a group of people who are appointed or elected to carry out a particular task or function. The word is derived from the Old French word "comité", which means "to entrust".
The word "committee" is spelled with a "t" after the "m". This is because the word is derived from the Old French word "comité", which has a "t" after the "m".
The words "comitee", "commitee", and "Comitee" are all incorrect spellings of the word "committee".
