C. EpidermopHytonExplanation
The correct answer is Trichophyton, Microsporum, and Epidermophyton. These three genera of Dermatophytes are known to affect epidermal tissue and keratinized tissue such as hair and skin. Trichophyton species are the most common cause of fungal infections in humans, affecting the skin, hair, and nails. Microsporum species primarily cause infections of the skin and hair, including ringworm. Epidermophyton species are responsible for causing infections of the skin, hair, and nails, particularly in the groin and feet. Keratinophyton is not a recognized genus of Dermatophytes and therefore not a correct answer.Rate this question:
