Answer 1

Option- A : The option A is the best to choose from the given four, we have the further explanation as below;

Lymph:"It is pale fluid that bathes the tissues of an organism, maintaining fluid balance, and removes bacteria from tissues."

Step-by-step explanation:

• Constituents of lymph:

1. lymphocytes,
2. Macrophages.

• Functions:

The lymphatic system helps maintain fluid balance in the body by collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream.
