# Bulk of lamina propria of the gingiva is made of collagen type:
a) I
b) II
c) III
d) IV
The correct answer is A. Type I.
The bulk of the lamina propria of the gingiva is made of collagen type I.
Explanation:
The lamina propria of the gingiva, a connective tissue layer supporting the gingival epithelium, primarily consists of collagen type I, which provides structural strength and resilience. Collagen type I is the most abundant collagen in connective tissues like the gingiva, while other types (e.g., II in cartilage, III in reticular fibers, IV in basement membranes) are less dominant in this context.
