Psychosocial therapies for autism spectrum disorder (ASD) combine:

A) structured educational services and psychoanalysis.
B) behavioral techniques and structured educational services.
C) cognitive-therapy and psychoanalysis.
D) psychotherapy and rational-emotive therapy.

Behavioral techniques and structured educational services have been shown to be effective in improving social communication, adaptive behavior, and reducing challenging behaviors in individuals with ASD. Other types of psychotherapy, such as psychoanalysis or cognitive-therapy, may not be as effective in treating the core symptoms of ASD. Similarly, rational-emotive therapy is typically not used as a primary treatment for ASD.
