• C. Encapsulation is the process of bundling data and code together into a single unit. This helps to protect the data from unauthorized access and modification, and it also makes the code more reusable. Encapsulation is often used in object-oriented programming.
• D. Protection is the act of keeping something safe from harm. This can be done in a variety of ways, such as through physical security measures, such as locks and alarms, or through electronic security measures, such as firewalls and intrusion detection systems.
