Correct option is D
A
Software Requirement Specification (SRS) document outlines the functional and non-functional requirements of a software system. The key characteristics of a good SRS are:
1.
Completeness: All requirements necessary for the development and operation of the software must be included.
2.
Consistency: The document should not contain conflicting requirements.
3.
Clarity: The requirements must be clearly and unambiguously stated to avoid misinterpretation.
However,
reliability is not a characteristic of the SRS itself; it is a quality attribute of the software system to be developed. The SRS specifies what needs to be done to achieve reliability, but reliability is not a characteristic of the document.

Key Characteristics of a Good SRS:
·
Completeness: Every functional and non-functional requirement should be included.
·
Consistency: There should be no conflicting or contradictory requirements.
·
Clarity: Every requirement should be easy to understand, with no ambiguity.
·
Modifiability: The document should be structured so that changes can be made easily.
·
Verifiability: Each requirement must be testable and measurable.

Importance of SRS:
· Acts as a foundation for software design and development.
· Helps in reducing misunderstandings between stakeholders and developers.
· Facilitates validation and verification during the software lifecycle.
Additional Knowledge:
·
Reliability is a
non-functional requirement of the software that measures the probability of failure-free operation under defined conditions.
· It is achieved by addressing requirements like fault tolerance, error handling, and recovery, which are often specified in the SRS but not characteristics of the document itself.
