A Correct answer
Explanation

Mast cells are immune cells that contain granules with histamine and heparin. They are abundant in areolar tissue (a type of loose connective tissue found throughout the body, especially under skin and around blood vessels). Areolar tissue provides a strategic location for mast cells to respond rapidly to pathogens, allergens, and tissue injury by releasing inflammatory mediators.
