C. Salivary, Thyroids, Adrenal, Ovary, Testis
D. Adrenal, Ovary, Testis, Salivary, Liver,

Answer 1

Hint: There are various glands located in different parts of the body. Theses glands come under two categories:
> Endocrine glands-Endocrine glands are those glands which pour their secretion directly into the bloodstream. These are also known as the ductless glands. These secrete the chemical messengers also known as hormones.
> Exocrine glands- Exocrine glands are those glands which have ducts. These secrete enzymes which act as biocatalysts altering the rate of the chemical reactions going on in our body.

Complete answer:
To know the complete answer to the question, we must be well aware of the various glands in our body.
The endocrine system consists of all those glands which do not have ducts in them.
Pituitary Gland- These endocrine glands produce hormones which regulate the secretion of the various other endocrine glands. It is also known as the hypophysis cerebri. It secretes growth hormone, prolactin, Adrenocorticotropic hormone, thyroid stimulating hormone etc.
Adrenal glands- These are cap shaped glands present at the top of each kidney. These glands secrete steroid hormones.
Ovary and Testis are also categorized under the endocrine glands because the ovaries secrete the hormone estrogen and progesterone while the testis secretes the hormone testosterone.
Salivary glands are the exocrine glands. They pour their secretion saliva through the ducts.

Since now we are well aware of the various glands, therefore the correct answer to the question is Option B i.e. Pituitary, thyroid, adrenal, ovary, testis.

Note: Here it must be noted that the endocrine glands secrete hormones. The hormones are the chemical messengers which affect the functioning of our body. These are released in very small amounts and affect the growth and development of the body.
