-
Histamine
-
Nor-epinephrine
-
Glucocorticoid
-
Mineralocorticoid
A
Correct answer
Explanation
Histamine is a nitrogenous compound which gives a local immune response. Histamine is involved in the inflammatory response as well as it acts as a neurotransmitter. As a part of the immune response to foreign pathogens, histamine is produced by the mast cells and the basophil cells in the nearby connective tissue against the allergic reaction. Sneezing happens because of histamine-associated sensory neural stimulation.
