• C. Pyloric sphincter covers the opening of stomach into the duodenum
• D. None of these

Answer 1

The correct option is A The epiglottis covers the glottis

In man, even though both air and food go through the pharynx, food does not normally enter the windpipe because during swallowing of food the epiglottis a cartilaginous flap covers the glottis so that the food does not accidently move into the wind pipe.

So, option A is the correct option.
