UPSC Prelims 2022— Question 31

This question belongs to Digital Governance and tests Open-source Government Platforms. The distinction lies in the architecture, ownership, interoperability or public-service role of the digital platform. Familiar names can be misleading if the statement attributes the wrong technical model or governance arrangement. Option D is the keyed answer because 1, 2, 3 and 4 is the combination or identification that satisfies the conditions in the question. A useful way to solve the question is to separate the individual propositions from the answer-code combinations. A statement can look broadly reasonable while still being incorrect because it uses an absolute term, assigns a function to the wrong institution, confuses two related concepts, or places a feature in the wrong region or period. The keyed response should therefore be treated as the outcome of checking each proposition rather than as a memory-only exercise. Option A: 1 and 2 only — this is not the correct choice. It fails the question's test because it does not represent the required combination, institution, location, mechanism or historical association. The distractor is plausible only if a related concept is confused with the one actually asked. Option B: 2, 3 and 4 only — this is not the correct choice. It fails the question's test because it does not represent the required combination, institution, location, mechanism or historical association. The distractor is plausible only if a related concept is confused with the one actually asked. Option C: 1, 3 and 4 only — this is not the correct choice. It fails the question's test because it does not represent the required combination, institution, location, mechanism or historical association. The distractor is plausible only if a related concept is confused with the one actually asked. Option D: 1, 2, 3 and 4 — this is the correct choice under the final key. It matches the relevant Open-source Government Platforms principle and satisfies the question's wording. The exam-oriented takeaway is to identify the governing fact first and only then map it to the answer code. This reduces errors caused by choosing an option because one individual statement appears familiar. For database use, the classification and explanation should be read together: the subject gives the broad domain, the topic identifies the recurring UPSC theme, and the subtopic records the precise knowledge point tested. This also makes the question useful for later topic-wise search and revision.
