Ozone layer depletion was not noticed until 1979, while CFC’s have been around since 1920s because CFCs take time to enter the stratosphere and remain there for at least 60 years after their initial release.
Option: A
Explanation:
Ozone layer is found in stratosphere. Ozone plays a dual role in the environment. When it is in the ground surface zone it is a harmful gas but when its in the atmosphere it is a life saving layer which absorbs UV rays and protect human beings and animals from the harmful affect of poisonous gases.
Though ozone layer started depleting from 1920. But it came into notice from 1979 as CFCs take time to enter the stratosphere and remain there for at least 60 years after their initial release.

The drawbacks of the open-field system are as follows.
(1) Under utilisation of land due to remaining idle.
(2) Farmers slaughtered their animals in autumn and used to salt their meat for consumption in winter as there used to be no hay during the colder season.
(3) The farming land of families and individuals lay scattered all around. Hence, reaching a field took much time and was tedious.
(4) Paths and cart tracks led to land wastage significantly.
(5) After ploughing a field keeping them idle was a wastage of labour, resources and time.
(6) Diseases were rampant due to the common grazing ground of livestock.
