With reference to the evolution of living organisms, which one of the following sequences is correct ?

Option 3 is correct because it presents taxa in the proper broad evolutionary sequence: amphibian lineages (e.g., salamanders) trace back to the early terrestrial vertebrates of the Palaeozoic, making them older than the major reptile radiations of the Mesozoic; snakes (python lineage as squamate reptiles) therefore appear later than amphibians but before the major mammal radiations. Mammals, including marsupial lineages that gave rise to kangaroos, diversified predominantly in the Cenozoic after the Mesozoic; thus kangaroos are the most recent in this trio [2]. The other options mix groups out of this Paleozoic–Mesozoic–Cenozoic ordering and are therefore incorrect [1].
