B Correct answer
Explanation

Asthma primarily affects the respiratory tract, causing bronchial tube inflammation, constriction, and mucus production that makes breathing difficult. While lungs contain the affected airways, 'respiratory tract' more precisely describes the system impacted. Asthma doesn't directly affect heart or liver function.
