The secondary palate develops from the fusion of which embryonic structures?

A Medial nasal prominences
B Mandibular prominences
C Frontonasal prominence
D Lateral palatine shelves ✓

Correct answer: D. Lateral palatine shelves

Explanation

The secondary palate forms from the fusion of the lateral palatine shelves, which are outgrowths of the maxillary prominences. The medial nasal prominences form the primary palate and the philtrum. The frontonasal prominence contributes to the forehead and nasal bridge. The mandibular prominences form the lower jaw.
