Which of the following characteristic features always holds true for the corresponding group of animals?

  1. Possess a mouth with an upper and a lower jaw – Chordata
  2. 3-chambered heart with one incompletely divided ventricle – Reptilia
  3. Cartilaginous endoskeleton – Chondrichthyes
  4. Viviparous – Mammalia

Answer

(3) Cartilaginous endoskeleton – Chondrichthyes

Solution

As per NCERT, all members of class Chondrichthyes have a cartilaginous endoskeleton — always true.

∵ Cyclostomes and lower chordates (urochordates, cephalochordates) are jawless chordates, option (1) is not always true.

∵ Crocodiles have a 4-chambered heart, option (2) is not always true.

∵ Egg-laying mammals (e.g. Ornithorhynchus) exist, option (4) is not always true.
