The correctly spelled word is "commander". It is a noun that means a person who is in charge of a group of people, especially in the armed forces. The word comes from the Latin word "commandare", which means "to order".
The other options are incorrect because they are not spelled correctly. "Comander" is missing the "d" in the middle. "Commandor" is missing the "n" at the end. "Comandar" is missing the "e" at the beginning.
I hope this helps!
