The word "Vaccination" has been derived from a Latin word that relates to the cow. The correct option is option 3, "Cow".

Vaccination comes from the Latin word "vacca," which means cow. This is because the first ever vaccine was developed for smallpox, and it involved using material from cows. Edward Jenner, an English physician, noticed that milkmaids who had contracted cowpox, a disease that affected cows, seemed to be immune to smallpox. He conducted an experiment where he took material from cowpox blisters and injected it into a young boy, effectively inoculating him against smallpox. This marked the beginning of vaccination as a method of preventing diseases.

The term "vaccination" was then coined to describe this technique of using material from cows to protect against smallpox. Later, the concept of vaccination was expanded to include the use of other animals for vaccine development, but the term itself originated from the relationship between cows and the early smallpox vaccine.
