Mike is:
A. Living in Bad faith.
Step-by-step explanation:
The concept of Bad faith is one of the main issues that the existentialists like Sartre describe.
It is something that the people of the world do faced by the societal pressures around them to conform to.
They just accept the societal values as they are and never contemplate about them because it would be more painful to do so and instead just work the way the society tells them to keep working.
This is what the person in Bad faith does.
