1. The question asks to identify a Brahmavadini who composed some hymns of the Vedas. 2. Brahmavadini refers to women scholars or expounders of sacred knowledge (Brahman) in ancient India. 3. The Rigveda, the oldest of the Vedas, contains hymns attributed to several women seers (rishikas). 4. Among the options given, Lopamudra is traditionally recognized as one of these rishikas. She is credited with composing hymns in the Rigveda (e.g., RV 1.179, a dialogue between her and her husband, sage Agastya). 5. Gargi Vachaknavi was a famous philosopher known for her intellectual debate with Yajnavalkya in the Brihadaranyaka Upanishad, demonstrating her profound knowledge, but she is not primarily known as a composer of Vedic hymns. 6. Leelavati is associated with the famous mathematical treatise 'Lilavati' written by Bhaskara II in the 12th century CE, much later than the Vedic period. 7. Savitri is a revered figure associated with a famous story in the Mahabharata and the Gayatri Mantra (addressed to Savitr, a solar deity), but not typically listed as a composer of specific Vedic hymns in the same way as Lopamudra.
