Approach

Model-Driven Architecture (MDA)
Model-Driven Engineering (MDE)

Scope

Concerned with all aspects of the software engineering process — including model-based requirements engineering, software processes for model-based development, and model-based testing
Focuses on the design and implementation stages of software development using a subset of UML models; proposed by the OMG as a new software development paradigm

Correct Answer

(1) Model-Driven Architecture (MDA),Focuses on the design and implementation stages of software development using a subset of UML models; proposed by the OMG as a new software development paradigm
(2) Model-Driven Engineering (MDE),Concerned with all aspects of the software engineering process — including model-based requirements engineering, software processes for model-based development, and model-based testing

Explanation

MDA focuses on design and implementation stages and was proposed by the Object Management Group (OMG). MDE is the broader concept — it is concerned with all aspects of the software engineering process, including topics that are part of MDE but not MDA, such as model-based requirements engineering and model-based testing.
