Graves’ disease is caused by the excessive secretion of thyroid hormones, leading to increased metabolism and weight loss.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Endocrine Disorders
Thyroid hormones are secreted by the thyroid gland, not the adrenal gland.
Ref: NCERT Class 11 Biology Chapter 19: Chemical Coordination and Integration Pineal Gland and Thyroid Gland
Thyroid hormones (T3 & T4) regulate the body's metabolic rate and energy balance.

Correct option is C, Two benzene rings. In Endocrinology, the accurate description is Two benzene rings, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Two benzene rings does in Endocrinology. Then Two benzene rings is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Two benzene rings. 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.
Answer: B) Decrease blood calcium. For Endocrinology, once you lock onto the key mechanism or definition, Decrease blood calcium is the clear fit. If you restate the concept in your own words, Decrease blood calcium is the option that correctly names the structure, process, or principle asked for in Endocrinology. So Decrease blood calcium is the clean, accurate selection. If a similar stem appears later, start from the same core fact and you will land on the same kind of answer. In class notes, highlight this same phrase next to the related diagram so the wording and the picture reinforce each other.

T3 and T4 (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: T3 and T4 is the option that correctly names the structure, process, or principle asked for in Endocrinology. That reasoning supports T3 and T4. 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 T3 and T4 from memory, then reveal the letter — that habit builds real recall for Endocrinology.
