Answer 2

Source : Britannica – “intension” indicates the internal content of a term or concept that constitutes its formal definition; and “extension” indicates its range of applicability by naming the particular objects that it denotes. For instance, the intension of “ship” as a substantive is “vehicle for conveyance on water,” whereas its extension embraces such things as cargo ships, passenger ships, battleships, and sailing ships. 

Increasing intension is when each term connotes more attributes than the one preceding it.  

 

For above question correct arrangement would be – 

Animal → Mammal → Feline → Tiger .  

 

 

Ans : Option C.
