The correct answer is option 2, Raidas. Raidas, also known as Ravidas, was considered to be the preceptor of Mirabai. A preceptor is a teacher or spiritual guide who imparts knowledge and guidance to a disciple.

Raidas was a prominent poet-saint of the Bhakti movement, which emerged in medieval India as a form of devotional worship. He belonged to the lower caste of cobblers and is known for his poems and teachings that emphasized social equality and love for God.

Mirabai, on the other hand, was a 16th-century Rajput princess who renounced worldly life to devote herself completely to the worship of Lord Krishna. She was an ardent follower of the Bhakti tradition and expressed her devotion through her poems and songs. Raidas influenced and inspired Mirabai with his teachings, making him her preceptor.

It is important to note that while all the options given in the question are notable figures in the Bhakti movement, Raidas specifically had a significant influence on Mirabai`s spiritual journey, earning him the title of her preceptor.
