Concept:Data integrity means preserving the accuracy, consistency, and completeness of data throughout its entire life cycle.
Explanation:Maintaining the value and content of data primarily means ensuring the data remains unaltered, uncorrupted, and authentic.
This is directly achieved by the principle of data integrity. It prevents accidental changes, deletion, or unauthorised modification that would reduce the usefulness of the stored information.
In contrast, data coding focuses on efficient representation and processing of data. Data secrecy and data security concentrate on protecting data from unauthorised access and external threats.
None of these focus on preserving the original meaning and worth of the data itself in the way integrity does.
Therefore, the phrase matches the purpose of data integrity.
Answer:B. integrity
