Step-by-step explanation:
The country with a leaf on its flag that has 11 points is b) Australia.
The flag of Australia, also known as the Australian National Flag, features a dark blue field with the Union Jack in the canton (upper hoist-side corner) and a large white seven-pointed star beneath it. To the right of the Union Jack is a representation of the Southern Cross constellation, which consists of five stars. One of these stars, known as the Commonwealth Star, has seven points, symbolizing the states and territories of Australia. Therefore, the leaf on Australia's flag has 11 points in total.
