Which sentence uses correct punctuation? we had a heavy, meal and soon wanted warm snuggly naps. we had a heavy hot meal and soon wanted warm, snuggly naps. we had a heavy hot meal and soon wanted warm snuggly naps. we had a heavy meal and soon wanted warm, snuggly naps. ((my answer))

The correct answer is the third sentence: “We had a heavy hot meal and soon wanted warm snuggly naps.”

In this particular sentence a comma is not needed as the coordinating conjunction “and” joins an independent clause (“We had a heavy hot meal”) and a phrase which is not a complete clause; that is to say, it has not subject and verb, and it does not convey a complete thought (“soon wanted warm, snuggly naps.”)
