Answer: (A)

Verified step by step guidance

1. Understand the definition of reticular connective tissue: It is a type of connective tissue characterized by a network of reticular fibers made of type III collagen. These fibers form a soft skeleton (stroma) to support the lymphoid organs.
2. Identify the primary locations of reticular connective tissue: It is predominantly found in lymphoid organs such as the spleen, lymph nodes, and bone marrow.
3. Consider the statement: 'Reticular connective tissue is found in all lymphoid organs and tissues.' This implies that every lymphoid organ and tissue contains reticular connective tissue.
4. Evaluate the accuracy of the statement: While reticular connective tissue is common in many lymphoid organs, it is not present in all lymphoid tissues. For example, the thymus primarily contains epithelial cells rather than reticular fibers.
5. Conclude whether the statement is true or false based on the evaluation: Since not all lymphoid tissues contain reticular connective tissue, the statement is false.
