b. Antigen
c. Lysozyme
d. Antibody

1. an antimicrobial chemical
2. glycoprotein that binds to a specific antigen
3. function in both innate and adaptive immunity
4. a foreign substance that provokes an immune response

The immune response is defined as the our body fights against foreign bodies such as germs, bacteria, viruses, etc.

Explanation:

a. Leukocytes

-- 3. function in both innate and adaptive immunity.

  Leukocytes are the white blood cells which defends the body against any infections and diseases.

b. Antigen

-- 4. a foreign substance that provokes an immune response.

   Antigens are bodies that provokes or stimulates the immune system.

c. Lysozyme  

--- 1. an antimicrobial chemical.

   Lysozyme  is an enzyme which is secreted by the in the milk, tears and saliva. It acts as an antimicrobial agent which cleaves the peptidoglycan component of the bacterial cell walls and leads to the death of the cell.

d. Antibody

-- 2. glycoprotein that binds to a specific antigen.

   Antibodies are secreted in the mucosa and in the blood. It binds to the toxins and the pathogens.
