  • A: Salamanders (clade Urodela)
  • B: Frogs (clade Anura)

Explanation

The text explicitly states: 'The amphibians are represented today by about 6,150 species in three clades: salamanders clade Urodela, 'tailed ones' , frogs clade Anura, 'tailless ones' , and caecilians clade Apoda, 'legless ones' .' Newts are a common name for a type of salamander, not a separate clade at this level.
