The correct option is C Nasopharynx
The pharynx makes up the part of the throat following the nasal cavity, and is comprised of three parts - the nasopharynx, followed by the oropharynx and the laryngopharynx. The laryngopharynx continues into the respiratory pathway anteriorly and the oesophagus posteriorly. Thus, the part of the pharynx immediately leading from the nasal cavity is the nasopharynx.
