Who among the following was a Brahmavadini who composed some hymns of the Vedas?

Lopamudra was a prominent female philosopher and scholar of the Vedic period. In the Rigveda, women who stayed back at gurukuls to pursue lifelong spiritual knowledge and composed hymns were known as Brahmavadinis. Lopamudra is credited with composing several hymns in the first book of the Rigveda. While Gargi was a famous philosopher who participated in intellectual debates, she is primarily associated with the Upanishads rather than being a composer of Rigvedic hymns. Leelavati was a mathematical treatise written by Bhaskara II in the 12th century, and Savitri is a solar deity or a legendary character from the Mahabharata, not a composer of the Vedas. Thus, Lopamudra is the correct answer.
