Solution
The correct option is D Tonsils
Tonsils are found in the pharynx and help in fighting infections. They are the first line of defence against illness. They produce WBCs.
A cartilaginous flap called epiglottis prevents the entry of food into the glottis (opening of the windpipe) during swallowing. The food enters the food pipe through the gullet.
A fleshy extension at the back of the soft palate which hangs above the throat is uvula. It helps in swallowing.
