Select the correct text in the passage. Which concept explained in the paragraph means that data remains hidden from the outside world?
All programs that we write in an OOP language consist of two elements: program code and data. Encapsulation is an object-oriented programming concept that binds together the data and the functions that manipulate the data. It keeps both the code and the data safe from outside interference and misuse. Binding properties and methods together provides controlled access to the data members and, therefore, ensures the security of the data.

Encapsulation is also closely linked with abstraction. Encapsulation prevents other programs from accessing the data directly, whereas abstraction refers to the feature of providing the functionality required, without disclosing the details of implementation.
