What is the most appropriate goal of Logotherapy?

The correct option is: To facilitate the client to find the meaning of his/her being.

Explanation:
Logotherapy is a school of psychotherapy founded by Viktor Frankl. It is based on the premise that the primary human drive is not pleasure (as suggested by Freud) or power (as suggested by Adler), but rather the "will to meaning." That is, the search for a life purpose.
Therefore, the most appropriate goal of Logotherapy is to assist and facilitate the client in discovering and finding personal meaning in their own existence and being.

Let's look at why the other options represent different therapeutic modalities:
• To unlearn faulty behaviour patterns: This is the primary goal of Behaviour Therapy (such as classical or operant conditioning techniques).
• Cognitive restructuring which in turn reduces anxiety: This is the core goal of Cognitive Behaviour Therapy (CBT).
• To increase an individual's self-awareness: While relevant to many therapies, it is particularly central to Humanistic/Gestalt therapies, whereas Logotherapy focuses specifically on the search for meaning.
