Vasopressin release increases in response to all EXCEPT:
The correct answer is D: Increase in extracellular fluid volume. In Endocrinology, this idea is central because it matches how the body actually works in everyday teaching examples. Put simply, the stem is asking for the statement that does not fit the usual rule, and Increase in extracellular fluid volume is that exception in the context of Endocrinology. That is why Increase in extracellular fluid volume is the option that holds up when you check it against basic physiology. When you revise, say the answer out loud with one short reason attached; that sticks better than rote lists. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.
