2. Encapsulation

3. Decryption

4. Fragmentation

The correct answer is: Encapsulation

The process of bundling data and methods together in software development is known as encapsulation. This principle is a fundamental concept in object-oriented programming, where the data (attributes) and the methods (functions or procedures) that operate on that data are packaged together into a single unit known as an object. Encapsulation serves several important purposes: 1. **Data Hiding**: By encapsulating data within an object, developers can control access to that data. This means that the internal state of an object can be protected from unauthorized access or modification from outside the object. It ensures that the object's data can be accessed or modified only through well-defined interfaces, promoting security and integrity. 2. **Modularity**: Encapsulation enhances modularity in software design. When data and the methods that manipulate that data are encapsulated, it allows developers to think in terms of discrete units (objects) that can be developed, tested, and maintained independently. 3. **Ease of Maintenance**: Changes made to the internal implementation of an object do not necessarily affect other parts of the program that use the object, as long as the object's interface remains consistent. This simplifies maintenance and reduces the risk of introducing bugs into other parts of the code. 4. **Reus
