Answer:
She enjoys instant gratification
Explanation:
Lets take a look at the options we have
A) She enjoys instant gratification
This seems correct due to the scenario using 'rewards herself'. But remember to check every option first.
B) There is no challenge in her life
This is incorrect due to the challenge she currently faces 'difficulty saving'
C) She lacks personal responsibility
This is a viable option but due to the scenario using 'rewards herself' we can assume she goes on shopping sprees after doing something good/getting her work done. The use of 'successful professional' also indicates that she is responsible, because y'know its hard to become successful without first being responsible.
D) Her co-workers are influencing her
Though the question mentions 'professional' and hints at work, the use of pronouns such as 'herself' are more direct and in this scenario we can assume that this option is incorrect.
Option A fits the scenario the best and is the answer.
