Which of the following causes increase in both GFR and renal plasma flow?

Glomerular filtration rate (GFR) is the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman&;s capsule per unit time.Renal plasma flows (RPF) the amount of plasma that perfuses the kidneys per unit time. Approximately 90% of the total constitutes the effective renal plasma flow, the poion that perfuses functional renal tissue, such as the glomeruli.Ref: Ganong&;s review of medical physiology; 24th edition; page no; 680
