Which term describes protecting against invalid data entering a software process by using mechanisms such as try, catch blocks?

• A. Readability
• B. Spiral Development
• C. Input Protection
• D. Exception Handling

Answer: (C)

Using try and catch blocks is about catching and handling errors that occur during program execution. This approach lets a program respond to unexpected problems—such as invalid data causing a runtime exception—by intercepting the issue, logging details, releasing resources, or continuing in a safe way instead of crashing. The term that best describes this behavior is exception handling. It’s distinct from input validation, which aims to reject or sanitize bad input before processing. Readability focuses on code clarity, and Spiral Development is a development process model, not about runtime error management. Input protection isn’t the standard label for this mechanism; exception handling is the precise concept here.
