Q.130) Frogs respire in water by skin and buccal cavity and on land by skin, buccal cavity and lungs.
A) The statement is false for both the environment
B) The statement is true for water but false for land
C) The statement is true for both the environment
D) The statement is false for water but true for land.
In water: Frogs respire mainly through their skin (cutaneous respiration) and also use their buccal cavity to some extent. So, this part of the statement is true.
On land: Frogs use their skin, buccal cavity, and lungs for respiration. However, the original statement says the same organs are used for both water and land, which isn't fully accurate because lungs are not used in water but are crucial on land.
Hence, option(3) is correct.
