The correct answer is option B, that is, adrenal glands.  

The endocrine glands also are known as ductless glands as they discharge hormones straightforwardly into the bloodstream. The secretions are discharged into the bloodstream for the brisk reaction. Adrenaline is secreted from adrenal glands, and gets discharged directly into the bloodstream and influences the ANS that monitors different activities of the body like heart rate, dilation of the pupil, secretion of saliva and sweat.
