- AGlucogon
- BCalcitonin
- CThyroxine
- ✓Paratharmone
$B.$ Thyroxine is secreted from thyroid gland. It stimulates the consumption of oxygen by metabolically active tissues and also increases the oxidation of glucose in tissues.
$C.$ Parathormone is secreted from parathyroid gland and increases calcium reabsorption from the bones and causes mobilisation of calcium in the blood.
$D.$ Calcitonin is secreted from the $C-$cells of thyroid gland and acts on bone and kidneys to reduce blood calcium level. Hence, blood calcium level is increased by parathormone. So, the correct answer is $'Parathormone'$.
