Explanation:

Oral herpes (HSV - 1) is mainly transmitted through saliva. Skin - to - skin contact (not the main mode for HSV - 1 in the context of oral herpes), blood transfusions (very rare for HSV - 1), and genital ulcers are more related to other types of herpes (like HSV - 2 for genital herpes in some cases). Saliva is the key medium for HSV - 1 transmission in oral herpes cases.

D. through saliva
