The correct answer is C. Both I & II.
The Bhakti movement was a Hindu devotional movement that originated in southern India in the 7th century CE and spread to northern India in the 12th century CE. The movement emphasized the importance of individual devotion to a personal god, rather than ritual or caste. The Bhakti movement resulted in a surge in Hindu literature in regional / vernacular languages mainly in the form of devotional poems and music. Some of the most famous Bhakti poets include Kabir, Mirabai, and Tulsidas. The Bhakti movement also had a significant impact on Buddhism, leading to the development of new schools of thought such as Mahayana and Vajrayana.
Option A is incorrect because it only mentions Hindu literature. Option B is incorrect because it only mentions Buddhist text. Option D is incorrect because both I and II are correct.
