Answer:
Redundancy is the mechanism that occurs in database's data as the same data is stores in the multiple location.It creates repeated data by accident or for backup purpose.
The issues that arise due to the redundancy of the data is the storage space in database gets consumed and thus wastes the space in storing information in multiple locations.When any update occurs in the stored data's field value , it also has to be changed in the multiples occurrences.

Limitation
A person comes who does not understand what robot speaks
Interaction with existing dialogue would be made possible through speech recognition system
The system will work well as speech recognition has now been used in many functions and robots have also now become quite advanced

Oracle, DB2, and Microsoft SQL Server are examples of RDBMS. Therefore, the <u>correct option of this question is (c)</u> i.e. RDBMS.
A software used to store, query, and retrieve data stored in a relational database is referred to as a relational database management system (RDBMS). In RDBMS, data is represented in tables with rows and columns.
The RDBMS handles administrative functions such as managing data access, storage and performance. To perform these administrative services, RDBMS provides an interface between the database, applications and users.
Some features of RDBMS are described below:
- RDBMSs are more secure, faster and easier to work with.
- More than one user can have access to RDBMS at a point of time.
- RDBMS supports distributed databases.
- RDBMS can store a vast amount of data.
- Only the data in the form of tables is managed by RDBMS.
- Data redundancy is reduced in RDBMS using primary keys and indexes.
Thus, Oracle, DB2, and Microsoft sql server are example of RDBMS.
<u>While the other ptions (a) supply chain management and (b) erp applications are not correct because:</u>

- Enterprise resource planning (ERP) applications refers to software used in organizations to manage day-to-day business operations such as project management, risk management and compliance, procurement, accounting and supply chain operations.
