Answer:
The correct answer is B) A great change or revolt.
Step-by-step explanation:
The word revolution has several meanings and definitions, but almost exclusively, all of the definitions point to some type of change.
At first glance, option D could also look like a possible definition, but the single's action towards some goal can hardly be seen as a revolution.
Especially if you consider the fact that in option D you are just going against your boss and not the entire system.
