To effectively handle all exceptions in programming, it is essential to have a handler for exceptions. An exception handler is a block of code designed to respond to an exception when it occurs, providing a structured way to manage errors and unexpected situations while ensuring the program continues to run or gracefully shuts down.

Having an exception handler facilitates the detection and resolution of errors without crashing the program. It allows developers to define specific actions to take when different types of errors occur, enabling more robust and fault-tolerant code. This practice is critical for maintaining the reliability of software, as it helps to prevent unhandled exceptions that can lead to system instability or data corruption.

In contrast, the other options do not specifically address the need to handle exceptions effectively. Program redundancy refers to including extra components or functions to ensure reliability but doesn't directly provide a method for handling errors. Comprehensive documentation is essential for understanding the code and its functionality but does not actively manage exceptions during runtime. Increased system privileges can inadvertently expose the system to security risks and does not relate to exception handling directly. Therefore, having a dedicated handler for exceptions is the correct approach for robust error management in programming.
