Hey there!
A correlating conjunction is a conjunction that uses two or more words within a sentence to combine two fragments or subjects. Examples of this would be "Neither Sally nor Joe could go to the meeting today," where "neither...nor" are the conjunctions, or "Not only did we snowboard today, but we also went ice skating at the lake," where "not only...but...also" are the conjunctions.
A coordinating conjunction is just one word used for the same purpose. An example of this would be "Tim was able to attend the meeting, but Sally and Joe were not," where "but" is the only conjunction.
Based on this, your answer will be a coordinating conjunction, since only one word is used to put your example sentence together.
Hope this helped you out! :–)
