option B        

Explanation:

Progressive muscle recovery (PMR) is a method of controlled breathing which has been used successfully to manage stress and fear, ease depression and alleviate the symptoms of some forms of severe pain. Progressive relaxing of a body is based on a simple process of clenching, or contracting, one muscles class at a time caused by a recovery period of stress release.

Throughout the 1930s, Edmund Jacobson defined the methodology of incremental muscle relaxation and is focused on his theory that psychological quietness is a necessary result of brain relaxation. Nearly everyone can know about gradual muscle relaxation which needs just 10 minute to 20 minutes of training per day.
