Answers
Answer :
Cambridge English Dictionary defines 'jack in' as 'to stop doing something, often a job or something that you are not enjoying.'
Urban Dictionary defines 'jack out' as 'To leave work unannounced with no warning. To sneak out before the appropriate end of the work day. '
Cambridge English Dictionary defines 'jack up' as 'to increase the price of something suddenly and by a large amount.'
From the above definitions we can conclude that c) jack up is the correct option to fill in the blank in the given sentence. The correct sentence is :
Most of the service stations decided to jack up gas prices after the gas war among them ended.
The answer is D. None of these.
Jack or Jack out or Jack up does not fit in this context.
Jack in means log into something, there is no defined meaning for the phrase jack out, and the phrase jack up means injecting self with a drug.
So none of these actually are the appropriate words. Thus the answer is D. None of these.
