In which scenario is Nikki showing resilience to stress?

Nikki lost her job as an engineer $3$ months ago. At first, she was depressed, but she realized she wanted to change career paths and decided to register for night classes.

Nikki is interviewing for a new job. As the interview approaches, Nikki starts to have doubts about her abilities and considers withdrawing her application.

Nikki is in charge of a big project at work. Over the last month, she has started to feel tired, short$-$tempered, and her performance has declined.

Nikki has been working extra hours for the last month trying to land a new client. This morning Nikki woke up feeling sick with cold$-$like symptoms.
