There are different accurate statements about the variable scope that are mentioned above. The first is letter A. You can define the variable in a block easily. The next statement is letter B. Even if you are using different parallel blocks, you can use the same name for them.

Lastly, letter C is also an accurate statement because the parent name cannot be reused anymore. Variable scope is known to be an entity or a variable wherein the different details about it can only refer to the said item. Placing the name of the scope is important especially if it needs to be found immediately.
