Option 2 matches Bhakti Saints to their respective professions correctly.

I-Namdev (C) Tailor: Namdev was indeed a tailor by profession. He was a 13th-century poet-saint of Maharashtra, India who is significant to the Varkari sect of Hinduism.

II-Kabir (B) Weaver: Kabir was a 15th-century Indian mystic poet and saint, whose writings influenced Hinduism`s Bhakti movement. He was a weaver by profession.

III-Ravidas (D) Cobbler: Ravidas was an Indian mystic poet-saint of the Bhakti movement during the 14th to 15th century CE. He was a cobbler by profession.

IV-Sena (A) Barber: Sena belonged to the barber caste, and his poems often reflect this, even through metaphor - consider his metaphor of souls being "shaved".
