In cases of Vitamin C deficiency, which of the following tissues is the least impacted?

Explanation

Vitamin C deficiency primarily affects collagen-rich structures such as gingival fibers, periodontal ligaments, and blood vessels in the gums, leading to weakened tissue integrity and bleeding. However, the epithelial lining of the mucosa is comparatively less affected because it contains less collagen and is not as dependent on Vitamin C for maintenance.
