Among the following official document names, which one is commonly associated with government policy papers issued in India?

Introduction / Context:
Governments often release formal documents to explain or justify policies, propose reforms or report on important issues. These documents sometimes have standard colour based names, such as white paper or green paper, which carry particular meanings in administrative practice. This question checks whether the learner can identify which of these names is most commonly associated with policy documents released by the Government of India.

Given Data / Assumptions:

Four types of named documents are listed as options: White Paper, Green Paper, Yellow Book and Blue Book.
The question asks which is associated with official policy documents in the Indian context.
It is assumed that the learner has encountered references to official reports and explanatory papers in news and textbooks.
There is no need for any calculation; the question depends entirely on conceptual knowledge.

Concept / Approach:
In India, the term white paper is commonly used for authoritative reports or policy papers issued by the government on specific issues, such as economic policy, telecom reforms or black money. These documents present the government's position, background facts and possible measures. Green papers, yellow books and blue books have different associations in various countries but are not the standard term for Indian government policy documents. Therefore, remembering the pairing of white paper with Indian policy reports leads to the correct answer.

Step-by-Step Solution:
Step 1: Recognise that the question is about the typical name of a policy related government document in India. Step 2: Recall that Indian governments at the central level have released documents called white papers on various topics, such as the economy or specific sectors. Step 3: Understand that white papers usually provide background, analysis and proposed policy directions, and may be tabled before Parliament or shared with the public. Step 4: Note that the term green paper is more commonly associated with preliminary consultation documents in some other countries and is not a widely used official label in the Indian setting. Step 5: Recognise that yellow book and blue book have different uses, often in foreign contexts, and are not the typical names for Indian policy papers. Step 6: From this comparison, conclude that White Paper is the correct choice.

Verification / Alternative check:
To verify, one can recall examples from news reports or budget discussions where the Government of India has released a white paper on the state of the economy, specific schemes or sectors. Such references are frequent in parliamentary debates and media coverage. Standard general studies books also mention white papers when explaining how governments communicate policy positions. The absence of similar frequent references to green papers or blue books in the Indian context supports the conclusion that white paper is the correct answer here.

Why Other Options Are Wrong:
Green Paper: The term is used in some other countries to describe consultative documents, but it is not the mainstream label for Indian government policy documents.
Yellow Book: This phrase has different meanings in other contexts, such as financial documents or technical standards, and is not commonly used as a name for Indian policy reports.
Blue Book: Often associated with diplomatic or foreign affairs documents in some nations, but it is not the standard term for policy documents issued by the Government of India.

Common Pitfalls:
Candidates sometimes assume that any colour based term might be used interchangeably, leading them to guess randomly among the options. Another pitfall is to confuse foreign administrative traditions with Indian practice. To avoid such mistakes, learners should connect white paper specifically with Indian policy documents and reasonably remember that the other colour names in the options are distractors or more relevant to other countries. Building awareness through reading news and government releases further reinforces this association.

Final Answer:
The official document name that is commonly associated with government policy papers in India is the White Paper.
