To answer this question, the user needs to understand the purpose of import statements in programming.
Option A: This option is incorrect. Import statements have nothing to do with declaring variables. Import statements are used to access classes, functions, and other resources from external modules.
Option B: This option is correct. One of the main advantages of using import statements is that they allow you to refer to a class without having to use a prefix. For example, if you import the "math" module in Python, you can use the "sqrt" function without having to write "math.sqrt" every time.
Option C: This option is incorrect. Import statements are not used to avoid calling methods. In fact, import statements are often used to make it easier to call methods from external modules.
Option D: This option is incorrect. Import statements are not used to import images. They are used to import code from external modules.
Therefore, the correct answer is:
The Answer is: B. To refer to a class without using prefixes.
