Insulin is produced by the

Show the answer and working

Answer: C

Insulin: pancreas.

Trap A Mismatches hormones and functions: Insulin (pancreas) lowers blood glucose; ADH (pituitary) reduces urine volume; adrenaline prepares for 'fight or flight'; thyroxine controls metabolic rate.

Trap B Gives the job of a neighbouring structure or stage: Learn structures as pairs of 'name → one job' and contrast neighbours: ribosome makes protein, mitochondrion releases energy; cochlea hears, semicircular canals balance. When two options sit in the same organ or process, ask which one does exactly the job in the stem.

Trap D Excretion misconceptions: Excretion removes metabolic wastes: kidneys (urea, water, salts), lungs (CO2, water), skin (sweat). Egestion of faeces is not excretion. Plants excrete O2, CO2, and store wastes in leaves/bark.
