oops design feature vs other programming models

I am going through the concepts of OOPS and I am wondering what is the unique design feature that makes Object Oriented Programming different than other programming models ?

• It uses mathematical logic for computer programming.
• It describes the desired outcome of a program without explicitly listing the steps that need to be carried out.
• It specifies the steps the program must take to reach the desired state.
• It is broken down into discrete units capable of receiving messages, processing data, and sending messages onto other units.

I am stuck on this question.
