Option (ग) 'आराध्य का नाम जपना' is the correct answer. In the bhakti context of Raidas's poetry, 'राम रट लागी' refers to the continuous chanting or jap of the Lord's (आराध्य) name. The word 'रट' implies the repetitive utterance or jap of the divine name, and 'लागी' signifies that this practice has become firmly attached to the devotee's heart. Therefore, the line expresses the deep spiritual emotion of chanting the deity's name, making option (ग) the most appropriate choice.
