Answer 1

The correct answer is:a. Sensitized T lymphocytes play a leading role in the pathogenesis.Explanation:In the fourth type of allergic reactions, known as delayed-type hypersensitivity (DTH), sensitized T lymphocytes play a crucial role in the pathogenesis. This type of reaction typically takes 48-72 hours to develop after exposure to the allergen. The mechanism involves the activation of T cells, which then release cytokines that recruit macrophages and other inflammatory cells to the site of the allergen. This leads to tissue damage and the characteristic signs of a delayed-type hypersensitivity reaction.
