The correct answer is: Parathyroid and Suprarenal
Parathyroid and Adrenal are the endocrine glands. Adrenal glands are the pairs of endocrine glands situated immediately above the kidneys. Hence they are also known as suprarenal glands.

Parathyroid glands are the two pairs of endocrine glands situated behind the thyroid gland in higher vertebrates. They produce parathyroid hormone, which controls the amount of calcium in the blood. The thymus is a temporary endocrine gland as its secretion decreases with age, while the pancreas, testis, and ovary are an example of heterocrine glands.
