Intranuclear inclusions are characteristic features seen in both Herpes Simplex and Oral Hairy Leukoplakia. In Herpes Simplex infection, intranuclear inclusions, known as Cowdry Type A inclusions, are observed in affected cells. These inclusions are formed by the virus replicating within the nucleus of the cell. In Oral Hairy Leukoplakia, caused by the Epstein-Barr virus (EBV), intranuclear inclusions known as 'Owl's eye inclusion bodies' can be seen in the epithelial cells of the oral mucosa. Therefore, option B is correct as intranuclear inclusions are associated with both Herpes Simplex and Oral Hairy Leukoplakia.

In the context of the other options:

A. Influenza and Mononucleosis do not typically present with intranuclear inclusions.

C. Chickenpox and Shingles are caused by varicella-zoster virus and typically do not exhibit intranuclear inclusions.

D. Measles and Rubella do not commonly display intranuclear inclusions in affected cells.
