Dr. Feldman is a cognitive-behavioral therapist whose approach to helping clients has been greatly influenced by Buddhism. It is likely that his therapeutic approach is based on the concepts of:

A) metamorphosis and rebirth.
B) mindfulness and acceptance.
C) immortality and reincarnation.
D) hope and change.

Dr. Feldman's therapeutic approach is likely based on the concepts of mindfulness and acceptance, which are key principles in Buddhism. These concepts involve being aware and present in the moment, and accepting one's thoughts and emotions without judgment. This approach aligns with cognitive-behavioral therapy, which focuses on changing negative thought patterns and behaviors. Metamorphosis and rebirth, immortality and reincarnation, and hope and change are not necessarily central concepts in Buddhism or Dr. Feldman's approach to therapy.
