What is the main structural difference between enveloped and nonenveloped viruses?

A) Enveloped viruses have their genetic material enclosed by a protein or phospholipid coat.
B) Nonenveloped viruses have only a phospholipid membrane,while enveloped viruses have two membranes,the other one being a protein capsid.
C) Enveloped viruses have a phospholipid membrane outside their capsid,whereas nonenveloped viruses do not.
D) Both viruses have a capsid and phospholipid membrane;but in the nonenveloped virus the genetic material is between these two membranes,while in the enveloped virus the genetic material is inside both membranes.
