Answer 2

The gases respectively absorbed by alkaline pyrogallol and

oil of cinnamon are

(b) O₂ and O₃

Alkaline pyrogallol is used by aquatic plants for absorbing oxygen gas (O₂), we have seen that in biology experiments.

Oil of cinnamon absorbs ozone gas (O₃).

So, the gases absorbed by alkaline pyrogallol and oil of cinnamon are oxygen and ozone respectively.

Thus, option (b) is the correct answer.
