• B. Periosteum
• C. Mucoperiosteum
• D. An aponeurosis

Explanation: Posteriorly, the hard palate continues into the soft palate, whose fibrous skeleton is the palatine aponeurosis.

• B. Pharyngeal recess
• C. Pharyngeal tonsil
• D. Salpingopharyngeal fold

Explanation: The nasopharynx contains structures such as the pharyngeal recess, pharyngeal tonsil and salpingopharyngeal fold.
