B Correct answer
Explanation

Like all papillomma viruses, HPV produces infections only in keratinocytes of skin or mucous membrane. HPV infection is limited to the basal cells of stratified epithelium, the only tissue in which they replicate. HPV cannot bind to live tissues; it infects epithelial tissues through micro-abrasions or other epithelial trauma that exposes segments of the basement membrane.
