The correct answer is: A. functional modularization.
Structured programming is a programming paradigm that emphasizes the logical flow of control and the modularization of code. It was developed in the 1960s and 1970s as a way to improve the quality and reliability of software.
Functional modularization is a key principle of structured programming. It involves breaking down a program into smaller, independent modules, each of which performs a specific task. This makes the program easier to understand, debug, and maintain.
The other options are not correct.
- Decentralization of program activity is not a principle of structured programming. It is a principle of distributed computing.
- Localization of errors is a goal of structured programming, but it is not a principle.
- Centralized processing is not a principle of structured programming. It is a characteristic of some computer architectures.
I hope this helps!
