The Correct Option is A, B
Solution and Explanation
Step 1: Recall role of immune cells.
Allergic reactions involve IgE antibodies, which bind to specialized immune cells. When allergens bind to IgE, these cells release histamine, causing allergy symptoms.
Step 2: Identify the correct cell type.
Mast cells have high-affinity receptors (FcεRI) for IgE. They store histamine in granules and play a central role in allergic responses.
Step 3: Conclusion.
Thus, the correct answer is mast cells.
