A. Cartilage
B. Lymph
C. Blood
D. Both B and C

Answer 1

Hint: Connective tissues help in connecting and also help to hold our body together. They provide internal support and protect the body. They are found in every part of the body. Different types of connective tissues are present in the body. They can be fluid and solid.

Complete answer: Blood is a connective tissue or a transport fluid. It is mainly composed of plasma and formed substances. It helps in the transportation of gases, nutrients, and water. It is pumped by the heart to the different parts of the body. It is mesodermal in origin and helps in connecting body systems, transports oxygen, and nutrients to all the parts of the body. It also helps in the removal of waste products. It has an extra-cellular matrix known as plasma with erythrocytes, lymphocytes, and platelets floating in it. It provides internal support and maintains the form of the body. Erythrocytes or red blood cells contain a pigment known as haemoglobin, which helps in oxygen transportation. There are different types of lymphocytes in our body that play a vital role in immune defense whereas platelets help in blood coagulation. Lymph is similar to blood except it lacks blood proteins, red blood cells, platelets, and plasma proteins. It is also a fluid connective tissue. It flows through the lymphatic vessel and helps in maintaining immunity.
Hence, the correct option is D, i.e., Both B and C.

Note: Blood and lymph are a type of fluid connective tissue that circulates in an extracellular matrix. It contains various cell types that are formed in bone marrow by the process of haematopoiesis.
