Which of the following is true about psychological assessments?

Psychological assessments are designed to evaluate various aspects of an individual's mental processes, behaviors, and emotional functioning. The correct answer highlights that these assessments provide insights into emotional functioning, which can include areas such as mood, emotional regulation, and interpersonal relationships. By exploring a person's emotional state, these assessments can help clinicians understand underlying issues that may be affecting mental health and guide appropriate interventions.

Furthermore, psychological assessments are not limited to a single purpose. They serve numerous applications beyond merely educational or clinical settings, such as in organizational psychology, forensic psychology, and research. They also often include components that assess cognitive abilities, making option C inaccurate. Additionally, while clinical environments frequently utilize these assessments, they are not confined to just those settings, which makes option D misleading. Thus, option B correctly acknowledges the broad significance of psychological assessments in understanding and addressing emotional functioning specifically.
