Solution

The correct option is B Glottis
The lowest part of pharynx is the laryngopharynx. It has two apertures, the anterior slit is 'glottis', through which it opens into the larynx and the posterior slit is 'gullet', which leads to the oesophagus.
Thus, larynx opens into the pharynx by glottis. The glottis bear a leaf-like a cartilaginous flap, called the 'epiglottis'. Epiglottis cover the glottis during swallowing, to prevent the entry of food into it.
Hence, the correct answer is B.
