What causes verruca?

An infectious virus
A parasite
Injury
Vitamin deficiencies

The correct answer is: An infectious virus

Verruca, more commonly known as a wart, is caused by an infectious virus known as the human papillomavirus (HPV). This virus enters the skin through small cuts or breaks and causes the skin cells to grow rapidly, resulting in the formation of a wart. Options B and D, a parasite and vitamin deficiencies, do not have any direct correlation to the development of warts. Option C, injury, can potentially create an opening for the virus to enter but is not a direct cause of verruca. Therefore, option A is the most accurate answer as it directly relates to the cause of verruca.
