The correct option is B) Nath-Panthis. Gorakhnath was a key figure in the Nath tradition or Nath Sampradaya, and his followers are commonly known as Nath-Panthis. Gorakhnath (c. 10th or 11th century) was a Hindu yogi and saint. He is considered one of the two major founders of the Nath Sampradaya, alongside his guru Matsyendranath. The Nath-Panthis are followers of this tradition, known for their yogic practices and emphasis on Hatha Yoga. ‘Jogis’ is a term often used generally for yogis, but ‘Nath-Panthis’ is specific to this sect.
