Which perspective would focus on how an individual interprets an event and applies it to their behavior?

Biological

Cognitive

Social-cultural

Psychodynamic

I think the answer is cognitive but I'm not sure

Biological would be to do with genes and neurones, so we can rule that out. Psychodynamic is to do with the unconscious mind, so that's passive and therefore no intentional application is involved. Cognitive is all to do with schemas and how we see the world, so I believe you are correct. I don't think we study the social-cultural approach in the UK
