Correct option is A
The Varkari movement is a devotional movement in Maharashtra focused on the worship of Lord Vitthal (Vithoba) of Pandharpur. It emphasizes devotion through poetry and songs, especially by saints such as Namadeva, Eknath, and Jnandeva. These saints are well-known contributors to the Varkari tradition. However, Vigneshvara is not associated with the Varkari movement; he is traditionally recognized in other contexts, often linked to Shaivism or as a deity in other traditions, not as a Varkari saint.
Namadeva (Namdev) was a prominent Varkari saint and poet.
Eknath was a saint and a key figure in the Varkari tradition.
Jnandeva was also a Varkari saint known for his devotional poetry.
Vigneshvara is not linked to the Varkari movement, hence he is the correct answer here.
