only
D
only.
Text Solution
Verified by ExpertsThe correct answer is:
A
Here the volume of gas increases from 
to 
at constant temperature 
Since 
, it is obvious that the spontaneous (irreversible) isothermal expansion of a gas is accompanied by an increase in the entropy of the system and its surroundings considered together..
