Answer 1

The Correct Option is A

Step 1: Understanding the Concept
Geographical isolation occurs when physical barriers such as water or mountains separate populations of a species.

Step 2: Key Point
Darwin's finches on the Galapagos Islands became different species in isolation on different islands.
This is the standard example given.

Step 3: Compare the options
A mule is a sterile hybrid, so it is an example of reproductive isolation.

Final Answer:
Darwin's finches are an example of geographical isolation. \[ \boxed{\text{(A) }\text{Darwin's finches}} \]
