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.
