(d) Physiological barriers

Answer 2

Neutrophils, basophils, lymphocytes, eosinophils and monocytes are examples of cellular barriers.

Explanation: The correct answer will be (b) cellular barrier as:

• Neutrophils, basophils, lymphocytes, eosinophils and monocytes are different types of white blood cells (WBCs).
• These cells participate in various mechanisms of the innate and adaptive immunity of the body.
• The pathogenic foreign materials are eliminated by these WBCs. Hence, neutrophils, basophils, lymphocytes, eosinophils and monocytes are the cellular barriers of the body.
