Directions: Choose the appropriate word from the given options and fill in the blank. Her ___________ was the reason of her unpopularity and the fact that she had few friends at the organisation.

It's a stronger form of arrogance that specifically implies an off-putting, condescending attitude that would naturally lead to unpopularity and having few friends. Pride and arrogance are milder, while impertinence is about rudeness, not necessarily superiority.
