Answer :
Final answer:
Lyme disease is transmitted to humans directly through the bite of an infected tick, specifically the Ixodes tick or deer tick. Deer and white-footed mice are common hosts for these ticks, but they do not transmit the disease directly to humans. So the correct answer is option D.
Explanation:
The Lyme disease bacterium is passed onto humans directly from d. ticks. More specifically, the Ixodes tick, also known as the deer tick, is a primary vector for Lyme disease, and it can transmit it to humans through a bite. Although these ticks can live on hosts like deer and white-footed mice, it is the ticks, and not the hosts, who transmit the disease directly to humans. When an infected tick bites a human, it can transmit the bacteria that causes Lyme disease, thereby initiating an infection.
