The correct answer is Option 3: Raskhan.

Prem Vatika is a collection of poems that revolve around the life and divine love of Lord Krishna. It was composed by the renowned poet Raskhan, also known as Raskhan Khan or Sheikh Raskhan. Raskhan was a 16th-century poet who primarily wrote in the Braj Bhasha, a dialect of Hindi.

Raskhan was deeply devoted to Lord Krishna and is considered one of the major poets of the Bhakti movement, a devotional movement that emerged in medieval India. His poetry reflects his intense love and admiration for Lord Krishna and often explores themes of divine romance, spiritual longing, and the path to union with the divine.

Raskhan`s poems in Prem Vatika are characterized by their lyrical beauty, emotional depth, and vivid descriptions of Krishna`s life and divine play (leela). They portray various aspects of Krishna`s life, including his childhood exploits (Balaleelas), his enchanting presence, his divine love affairs (Radha-Krishna leelas), and his role as the universal divine incarnation.

In addition to Prem Vatika, Raskhan also composed other devotional works such as "Surdas Satsai," "Sri Krishna Gitavali," and "Radha Rasa Sudhanidhi." His poems continue to be celebrated and cherished by devotees of Lord Krishna, and his contribution to devotional literature has left a lasting impact on Indian culture and spirituality.

While other poets like Surdas, Bihari, and Kabir have also composed poems on Lord Krishna, the specific work "Prem Vatika" is attributed to Raskhan. Surdas, another prominent poet of the Bhakti movement, is well-known for his composition "Surdas Satsai" which also explores the life and teachings of Lord Krishna. Bihari and Kabir, on the other hand, have contributed to the devotional and philosophical traditions in their own unique ways but are not directly associated with the composition of "Prem Vatika."
