The correct answer is D. Collony. The correct spelling is colony.
A colliery is a coal mine. A colleague is a person who works with you in the same profession or organization. To collaborate is to work with someone else to produce something. A colony is a group of people who live in a new place away from their home country.
The word "collony" is not a real word. It is a misspelling of the word "colony."
