Which circuit brings oxygenated blood to the rest of the body other than the heart and lungs?

The systemic circuit carries oxygen-rich blood from the heart to the body's tissues, excluding the heart and lungs, and returns oxygen-poor blood to the heart. The pulmonary circuit carries blood between the heart and lungs, while the cardiac circuit supplies the heart muscle itself. Therefore, the systemic circuit is correct.
