Explanation / Answer

1. Detailed logical representation of entities associations and data element for the organization or business area is best described by Entity-Realtion Diagram(ER Diagram)

DFD defines the flow of data within system

So , the given statement is False

2. Computer display and the report generators help prototype how the systems look and feel. -True

Report generators and computer display helps analyst to analyze the data , requirements and relationship and hence help prototype how system "look and feel".

3. A logical grouping of objects that have the same attributes and behaviors is called object class.

Object class is the top level class that defines basic behaviour that all objects must possess.

Hence , the given statement is true

4. Association among the instances of one or more entity types that is of interest to the organization is known as Relationship.

Relationship allows the connection between 2 or more entities

So, the given statement is True

5.The use of previously written software resources especially the objects and components in new applications is known as reuse.

It allows better utilization of resources as well as time as we don't have to build the already built product but can re-use it. As a result, productivity gets increased.

So, given statement is true
