Complete answer:
A gland is a group of cells in an animal's body that produces substances for release into the bloodstream (endocrine gland) or into body cavities or its outer surface (exocrine gland).
There are two types of glands:
Endocrine glands secrete substances directly into the bloodstream.
Exocrine glands secrete substances into body cavities or its outer surface.

LIVER
The liver is large, reddish-brown organs that lie on the right side of the belly weighing about 3 pounds.
It is the largest gland. The liver is an exocrine gland that secretes bile into the intestine is also an endocrine gland and a blood filter.
The liver is a metabolic factory that synthesizes and breaks down a number of substances.
PITUITARY
It is a pea-shaped gland located at the base of the brain.
It is considered to be a master gland as it secretes many hormones to regulate the organs as well as the other glands.
It secrete different hormones: Growth hormone, Thyroid stimulating hormone, Adrenocorticotropic hormone(ACTH), Gonadotropic hormone, Follicle stimulating hormone, Luteinizing hormone, Prolactin, Melanocyte –stimulating hormone, Oxytocin, Vasopressin or antidiuretic hormone (ADH)
THYROID GLAND
It is located in the neck, ventral to the larynx and the major hormones produced by this gland are triiodothyronine and thyroxine.
Thyroxine is a hormone that regulates the metabolism of carbohydrates, proteins and fats in the body.
PANCREAS
It is located just below the stomach and is both exocrine and endocrine in function.
It secretes hormones such as insulin, glucagon, somatostatin and pancreatic polypeptide.

So the correct answer is (B) Liver.

Note: The main job of liver is to:
> Filter the blood coming from the digestive tract
> Liver detoxifies chemicals and metabolizes drugs.
