This phylogenetic hypothesis shows the major clades of chordates in relation to the other main deuterostome clade, echinodermata. derived characters are listed for selected clades; for example, only gnathostomes have a jaw. in some lineages, derived traits have been lost over time or occur in reduced form; hagfishes and lampreys, for example, are vertebrates with reduced vertebrae.
based on this phylogeny, which vertebrate groups would you expect to have lungs or lung derivatives?

B. is the correct answer because not all genes are actively coding,RNA is not code for protein synthesis, also DNA does not contain a number of segments that code for specific proteins.
