A. 1970's

Detailed Explanation

The concept of Object-Oriented Programming (OOP) first came into the picture in the early 1970s.

The programming language Smalltalk, developed at Xerox PARC, is considered the first fully object-oriented programming language. It introduced key OOP concepts like:

  • Objects

  • Classes

  • Inheritance

  • Message passing

Although OOP became popular in the 1980s and 1990s with languages like C++ and Java, the concept itself originated in the 1970s.
