A	Necrosis
B	Paranecrosis
C	Apoptosis
D	Amitosis
E	Meiosis

Explanation:

Detailed explanation-1: -The vestibular lamina (VL) forms the oral vestibule, creating a gap between the teeth, lips and cheeks. In a number of ciliopathies, formation of the vestibule is defective, leading to the creation of multiple frenula.

Detailed explanation-2: -Early tooth development relies heavily on components of major signaling pathways expressed by both epithelial and mesenchymal tissues. Among these, the Wnt, BMP, FGF, Shh and EDA pathways play important roles in guiding tooth development through initiation, budding and morphogenesis.

Detailed explanation-3: -The vestibule is formed by the proliferation of the vestibular lamina into the ectomesenchyme. The vestibular lamina is usually contrasted with the dental lamina, which develops concurrently and is involved with developing teeth.
