Which of the following statements is true regarding try-catch blocks?

The statement regarding try-catch blocks that is true is that multiple catch blocks can be used, but only one executes. In programming languages that support exception handling, such as Java and C#, a try block can be followed by multiple catch blocks to handle different types of exceptions. When an exception occurs, the try block is exited, and the runtime system checks each subsequent catch block in the order they are defined to find a matching type for the thrown exception.

Upon finding the first catch block that matches the type of the exception, that specific block will be executed to handle the exception. This ensures that the appropriate handling logic is applied depending on the nature of the error that arose. If a more specific exception type is caught by one of the catch blocks, that block will be executed first, while the others will be ignored. This design allows for more granular control over exception handling, making it possible to manage various types of errors differently.

The other options do not reflect the established behavior of try-catch constructs in programming. For instance, multiple catch blocks can indeed exist, allowing for different exception types to be handled distinctly. Additionally, catch blocks must follow the try block and are designed to manage exceptions, not to prevent or ignore them. Each of these
