Answer 1

The Correct Option is D

Step 1: Understand the origins of vaccination. Step 1: Vaccination's discovery is a key medical breakthrough. An English doctor noticed milkmaids with cowpox didn't get smallpox.
Step 2: Pinpoint the key figures and events.
Step 2: In 1796, Edward Jenner tested his idea. He inoculated James Phipps with cowpox material. The boy then didn't get sick from smallpox. This proved vaccination's concept.
Step 3: Analyze alternative possibilities.
Step 3:

Louis Pasteur: Later developed vaccines for rabies and anthrax in the 19th century and is a major figure in microbiology.
Walter Reed: Showed mosquitoes transmit yellow fever.
James Lind: Performed the first clinical trial and found citrus fruits cured scurvy.
Edward Jenner is credited with the smallpox vaccine and coined the term "vaccination" (from *vacca*, Latin for cow).
