Answer:
The correct answer is letter "A": negative inequity.
Explanation:
John Stacey Adams proposed the Equity Theory stating wages and work conditions are not the only factors that motivate employees at work. According to Adams worker look for a balance between their inputs such as effort, skills, abilities or commitment and outputs like recognition, reputation, praise or job security.
Negative inequity arises when individuals feel their outputs are undervalued in regards to their inputs and positive inequity when the outputs overvalue the inputs. Then, Sophia is feeling negative inequity since she believes it is necessary to work harder (effort) so the workload of her team (output) can be increased compared to smaller regional airports.
