Which of the choices below is an example of abstraction?

A) Baking a cake

B) Drawing a picture
C) Writing a poem
D) Using a computer

One example of abstraction is:

- Removing unnecessary details or complexity from a concept or problem, to focus on the essential aspects. This allows us to understand and work with the concept or problem more easily. For example, in computer programming, creating a function to perform a specific task instead of writing the entire code for that task each time it is needed is an example of abstraction. The function abstracts away the details of the code, allowing us to use it as a single entity. Similarly, in mathematics, using variables to represent unknown values or generalizing a pattern or equation is also an example of abstraction.
