Who is NOT associated with medicine?

In ancient and medieval India, a person is described as "associated with medicine" when they are a physician, surgeon, or deity linked to Ayurveda, the traditional Indian system of healing – typically shown by authoring a foundational Ayurvedic treatise or being venerated as the science's patron figure.

Checking each name in the question against this idea: Dhanvantari, Charaka, and Susruta are all figures whose identity comes from Ayurvedic medicine, while Bhaskaracharya's entire body of work lies in mathematics and astronomy.

• Dhanvantari – venerated in Hindu tradition as the deity of Ayurveda, worshipped as the physician of the gods and regarded as the source of Ayurvedic knowledge.

• Charaka – an ancient physician credited as a principal compiler of the Charaka Samhita, a foundational Ayurvedic treatise on internal medicine.

• Susruta – an ancient physician-surgeon credited as the author of the Susruta Samhita, a foundational Ayurvedic treatise on surgery.

• Bhaskaracharya (Bhaskara II) – a 12th-century mathematician and astronomer, author of works such as the Lilavati and the Siddhanta Shiromani, covering arithmetic, algebra, and astronomical calculation.

Three of the four names trace directly to an Ayurvedic treatise or to the deity of Ayurveda, while Bhaskaracharya's works are treatises on arithmetic, algebra, and astronomy with no medical content, confirming Bhaskaracharya as the one figure NOT associated with medicine.
