Answer:
It's option B. Eun Sun lacks perceived organizational support.
The reason I chose this option is that perceived organizational support means that an individual working for the company is receiving good remarks or support for their hard work done. This is exactly what Eun Sun is in need of but unfortunately, her boss, fails to understand this and instead keeps giving her a hard time. Now, only if he were to say things like, "thank you for your hard work," or " you did great", Eun Sun would probably want to work even harder and better. Supportive words and encouragement can take you far.
