In world geography and country nicknames, this question asks you to identify which country is popularly known as the "land of kangaroo", a nickname derived from a well known native animal.

Introduction / Context:
Many countries are associated with particular animals or symbols, and these associations often appear as nicknames in general knowledge questions. The phrase "land of kangaroo" is one such nickname. It connects a distinctive marsupial animal with the country where it is most famously found. Recognising these associations is basic world GK and frequently used in school level and competitive examinations.

Given Data / Assumptions:
The nickname in question is "land of kangaroo".
Kangaroos are large marsupials with strong hind legs and a pouch for carrying young ones.
The answer choices are France, Italy, Australia, and a very broad option labelled Africa.
We assume the question expects you to identify the country most strongly associated with kangaroos in popular and scientific literature.

Concept / Approach:
Kangaroos are native to Australia and nearby islands and are not naturally found in Europe or across the entire African continent. Australia has so many species of kangaroos and related marsupials that these animals have become part of its national identity, appearing in tourism logos, sports emblems, and cultural references. Therefore, connecting the nickname with the correct country is mainly a matter of recalling this strong association.

Step-by-Step Solution:
Step 1: Recall which country is most famous for kangaroos. That country is Australia. Step 2: Check the options and identify Australia among France, Italy, Australia, and Africa. Step 3: Eliminate France and Italy, which are European countries not associated with kangaroos in the wild. Step 4: Eliminate Africa as a whole, because while Africa has many unique animals, kangaroos are not among its native fauna. Step 5: Choose Australia, which matches both zoological reality and the well known nickname "land of kangaroo".

Verification / Alternative check:
School textbooks, documentaries, and tourism campaigns often highlight kangaroos as a symbol of Australia. The national airline logo, sports teams, and souvenirs frequently depict kangaroos. Wildlife distribution maps show that kangaroos are endemic to Australia and certain nearby islands, reinforcing the identification. No similar association exists between kangaroos and France, Italy, or the entire African continent.

Why Other Options Are Wrong:
France: Known for culture, cuisine, and landmarks like the Eiffel Tower, but not for kangaroos in its natural environment.
Italy: Famous for ancient Roman history, art, and architecture, with no major association with kangaroos.
Africa: While Africa contains diverse wildlife such as lions, elephants, and giraffes, it is not the natural home of kangaroos, which are strictly associated with Australia and nearby regions.

Common Pitfalls:
This question is generally straightforward, but some candidates may rush and accidentally mark Africa because it is a continent with rich wildlife. Others may not carefully read all options and misclick. A safe approach is to connect each nickname with a clear characteristic: for example, land of kangaroo with Australia, land of the rising sun with Japan, and land of a thousand lakes with Finland.

Final Answer:
The country known as the "land of kangaroo" is Australia.
