According to the text, which of the following statements about diapsids and their lineages are correct? Select all that apply

  • A: Diapsids are characterized by a single hole behind each eye socket.
  • B: The lepidosaurs lineage includes tuataras, lizards, and snakes.
  • C: Pterosaurs were among the earliest tetrapods to achieve flapping flight.
  • D: Mososaurs, a type of marine reptile, belong to the archosaur lineage.
  • E: The earliest known reptiles, which were diapsids, appeared approximately 310 million years ago.

Explanation

Option A is incorrect because diapsids have a 'pair of holes' on each side of the skull. Option D is incorrect as mososaurs belong to the lepidosaur lineage, not archosaurs. Options B, C, and E are directly supported by the text: lepidosaurs include tuataras, lizards, and snakes; pterosaurs were the first tetrapods to exhibit flapping flight; and earliest reptiles appeared around 310 million years ago and were diapsids.
