To determine the correct function that is used to read all the characters, let's analyze the options provided:

1. Read() - This function is commonly used to read data but does not specifically indicate that it reads all characters.
2. Readall() - The name suggests that this function reads all characters without limitation, making it a strong candidate.
3. Readchar() - This function likely reads characters individually rather than all at once.
4. Readcharacters() - While descriptive, it is not a standard function name in programming libraries.

Final Answer

The correct choice is Readall(), as it explicitly indicates the reading of all characters.
