Answer 1

Hint: Lymph is the liquid that flows via the lymphatic system. It is an organization made of lymph vessels and prevailing lymph nodes whose purpose, as the venous system, is to return fluid from the tissues to the central circulation. The lymphatic system is a complex of tissues and organs that assist in rid the body of toxins, waste, and other unnecessary materials.

Complete answer:
The fluid flowing in the lymphatic system is called lymph. It is a pale fluid containing specific lymphocytes that are liable for the immune responses of the body.
It transfers oxygen, nutrients, hormones, etc. to the body cells and transports carbon dioxide and other metabolic wastes, from the body cells to the venous system.
Lymph is enclosed in the lymphatic system which includes lymphatic capillaries, lymphatic vessels, lymphatic nodes, and lymphatic ducts.
Lymph holds fewer antibodies as compared to plasma. It just translocates lymphocytes and antibodies from the lymph nodes to the blood. Unlike blood flow, it is for all time unidirectional. It helps to preserve protein and destroy the attacking microorganisms and strange particles in the lymph nodes.
Lymph is obtained from the tissue fluid.
Therefore, only (ii), (iii), (iv) and (vi) are correct.

So, Option B is the correct answer.

Note: Some water along with various small water-soluble substances migrates out through the spaces between the tissue cells. By leaving the larger proteins and most of them figured elements in the blood vessels the blood flows through the capillaries in tissues. This fluid released out is known as the tissue fluid. When the tissue fluid goes into the lymphatic capillaries, it is called lymph.
