This question is missing the options. I've found the complete question online. It is as follows:

Lydia feels her manager, Denny, bullies her at every opportunity. Whenever their project hits a snag, Denny singles out Lydia and launches into a verbal tirade against her. On a few occasions, Denny has even threatened to fire Lydia due to her supposed "incompetence." What type of bullying behavior does Denny use to intimidate Lydia?

a. Overt aggression

b. Isolation

c. Social attack

d. Gunny-sacking

The type of bullying being used by Denny to intimidate Lydia is:

a. Overt aggression.

Explanation:

Denny is not isolating Lydia or sharing images of her that may hurt her socially. Nor is he accumulating his anger and irritations against her silently until, one day, finally exploding. Denny is being aggressive toward Lydia in a very open manner - that's why it's called overt aggression. He is not trying to hide or manage the way he feels. He clearly dislikes Lydia and is making a point of showing it, combined with dissatisfaction when the projects don't go well.

i honestly speaking this is too long
