The answer is: D. Narcissism
People with narcissistic personality generally have a really exaggerated sense of self-importance, which often make them feel that other people are 'beneath' in some ways.
We can identity this personality trait from the way Michel talk about himself.
- I see that what I have achieved is outstanding and something no one in the organization has the capacity to undertake.
- also believe that I do not just deserve a raise, but need one, since without me, let's face it, the place would simply fall apart.
Those two sentences indicates that Michel felt that he is more valued/important compared to his colleagues.
