Correct Answer » A Explanation

Ans;A. Carcinoma of lymph nodes

The structure marked as “B” in the picture above represents carina of trachea.

A ridge at the base of the trachea (windpipe) that separates the openings of the right and left main bronchi (the large air passages that lead from the trachea to the lungs). Also called tracheal carina.

• The mucous membrane of the carina is the most sensitive area of the trachea and larynx for triggering a cough reflex.

• Widening and distortion of the carina is a serious sign because it usually indicates carcinoma of the lymph nodes around the region where the trachea divides.
