Explain the concept of reflexology.

Reflexology is a therapeutic practice that involves applying pressure to specific points on the feet, hands, or ears, based on the belief that these points correspond to various organs and systems within the body. This technique is rooted in the idea that stimulating these reflex points can promote healing, improve circulation, and enhance overall well-being. Reflexology is not limited to just the feet or the treatment of foot ailments; it encompasses the hands and ears as well, making it a versatile form of therapy. The practice aims to restore balance and harmony by targeting these reflex zones, helping to alleviate stress and tension throughout the body.

The other options misrepresent the scope and application of reflexology. Focusing solely on hand massage techniques, treating only foot ailments, or concentrating exclusively on the ear would not encompass the full breadth of what reflexology practitioners offer. Hence, the correct choice accurately reflects the comprehensive nature of reflexology as a holistic and multifaceted practice.
