Which of the following statements is true about psychodynamic theories?

A) It is possible to scientifically test their fundamental assumptions.
B) Psychodynamic therapies are unaffordable for many people owing to their long-term, intensive nature.

Psychodynamic therapies typically require long-term, intensive sessions with a therapist, which can be costly and not affordable for many people. While some of the basic assumptions of psychodynamic theories can be scientifically tested, the nature of the therapy itself is often seen as unstructured and may not be preferred by everyone. Psychodynamic theories do not necessarily explain normal and abnormal behavior with separate, distinct processes.
