Fight-or-flight response is mediated mainly by:
Explanation
Sympathetic system (B) is the right choice. This sits at the heart of Endocrinology: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: the functional job described in the stem is exactly what Sympathetic system does in Endocrinology. That reasoning supports Sympathetic system. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write Sympathetic system from memory, then reveal the letter — that habit builds real recall for Endocrinology.
