Hint: Blood is a kind of fluid that flows in the body of vascular organisms. It is one of the most important components of the body as it helps in transportation of substances from one place to another throughout the body.

Complete Answer
Let's study blood in detail to better understand its functioning.
Blood is a red coloured fluid that consists of various organelles that work as independent units and carry out various metabolic processes. Following is a list of organelles of blood:
RBCs: It is an acronym for Red Blood Cells. They are also called Erythrocytes. They impart red colour to the blood due to the presence of compounds called haemoglobin on their surface. They carry oxygen from lungs to various organs of the body and Carbon dioxide from various organs of the body to the lungs. On an average a healthy body should have 4.7 - 6.1 million cells per micrometer.
WBCs: It is an acronym for White Blood Cells. They are also called leukocytes. They are responsible for eradicating harmful foreign bodies from the body. They engulf such foreign bodies and destroy them. These are amoeboid structures. On an average a healthy body should have 4500 - 11000 cells per microliter.
Platelets: It is a common name for thrombocytes. They are responsible for inducing clotting of blood at wounded areas. These are very important for managing wounds. They are irregular bodies. On an average a healthy body should have 450000 - 150000 cells per microliter.
Plasma: It is not one of cell organelles but is a very important part of blood as it constitutes fluidity of the blood. It is a yellow coloured fluid.

Thus, we can say that option D is the correct option that says that blood carries Oxygen, Waste and Food.

Note:
Blood being the transporter of the body carries many objects such as food products, excretory products, gases. It reaches every corner of the body thus, becoming one of the connecting channels for the entire body.
