**Core Concept**
The question is testing the student's understanding of a common pediatric condition characterized by respiratory symptoms, allergic manifestations, and a positive family history. This condition involves an abnormal immune response to environmental allergens, leading to inflammation and airway constriction.
**Why the Correct Answer is Right**
The most likely diagnosis is Atopic Asthma, a chronic inflammatory disease of the airways that is often associated with a family history of allergies. Atopic Asthma is characterized by airway hyperresponsiveness, inflammation, and reversible airflow limitation. The symptoms of breathlessness, running nose, and positive family history of allergies are classic presentations of this condition. The airway inflammation in Atopic Asthma is mediated by the release of histamine and other chemical mediators from mast cells, eosinophils, and other inflammatory cells.
