According to the ISO−9126 Standard Quality Model, match the attributes given in List-I with their definitions in List-II:
\(\begin{array}{llll} & \text{List I} & & \text{List II} \\ \text{(a)} & \text{Functionality} & \text{(i)} & \text{Relationship between level of} \\ &&& \text{performance and amount of resources} \\ \text{(b)} & \text{Reliability} & \text{(ii)} & \text{Characteristics related with} \\ &&& \text{achievement of purpose} \\ \text{(c)} & \text{Efficiency} & \text{(iii)}& \text{Effort needed to make for improvement} \\ \text{(d)} & \text{Maintainability} & \text{(iv)} & \text{Capability of software to maintain} \\ &&& \text{performance of software} \\ \end{array}\)
Choose the correct options from the ones given below:
- A.
\(\text{(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)}\) - B.
\(\text{(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)}\) - C.
\(\text{(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)}\) - D.
\(\text{(a)-(i), (b)-(ii), (c)-(iv), (d)-(iii)}\)

Show answer & explanation
Correct answer: C
Correct mapping: Functionality → characteristics related with achievement of purpose; Reliability → capability of software to maintain performance; Efficiency → relationship between level of performance and amount of resources; Maintainability → effort needed to make improvements.
Functionality: characteristics related with achievement of purpose. This means the software provides the required functions and meets specified requirements.
Reliability: capability of the software to maintain performance. Reliability concerns consistent correct operation and stability over time.
Efficiency: relationship between level of performance and amount of resources. Efficiency evaluates how well the software uses resources to achieve performance.
Maintainability: effort needed to make improvements. Maintainability covers how easily the software can be modified, fixed, or enhanced.
Therefore the correct pairing is: (Functionality) → (ii), (Reliability) → (iv), (Efficiency) → (i), (Maintainability) → (iii).
