Step 1: Understanding the Concept: 
The question asks for the primary aims of psychological counselling. Counselling is a professional relationship that empowers diverse individuals, families, and groups to accomplish mental health, wellness, education, and career goals. 
Step 2: Detailed Explanation: 
(A) Therapeutic: This is a primary aim. Counselling helps individuals overcome existing problems, such as anxiety, depression, or relationship issues. It aims to heal emotional distress. 
(B) Preventive: Counselling also aims to prevent problems before they become severe. For example, pre-marital counselling can help prevent future marital conflicts, and stress management workshops can prevent burnout. 
(C) Developmental: Counselling supports personal growth and development throughout the lifespan. This includes helping people navigate life transitions, improve self-esteem, enhance communication skills, and achieve their full potential. 
(D) All of these: Since counselling encompasses healing existing problems (therapeutic), preventing future ones (preventive), and fostering personal growth (developmental), all listed options are valid aims. 
Step 3: Final Answer: 
The aims of counselling are comprehensive and include therapeutic, preventive, and developmental goals. Therefore, the correct answer is "All of these".
