To improve access to holy Ganga water, the Central Government launched a scheme in the state of Bihar to deliver clean water of the river Ganga to domestic areas through the postal department. What is the name of this scheme?

Introduction / Context:
This question connects government schemes, the postal department and religious tourism. The Central Government launched a special scheme in Bihar to deliver holy Ganga water, known as Gangajal, to people's homes using the postal network. Identifying the correct name of this scheme is a typical current affairs based general knowledge task.

Given Data / Assumptions:

• The scheme relates to delivery of clean Ganga water to households.
• The state mentioned is Bihar, and the implementing channel is the postal service.
• The options include names of several different schemes and programmes.
• Only one option clearly refers to delivery of Gangajal through the post.

Concept / Approach:
The key to this question is to match the description with the most appropriate and specific scheme name. The word Gangajal directly refers to water from the river Ganga used for religious purposes. A scheme that aims to deliver such water to people through post offices is logically called the "Gangajal Delivery Scheme". Other options mentioned, such as Mission Bhagiratha, National Apprenticeship Promotion Scheme and Railway Travel Insurance, relate to very different policy areas and therefore can be ruled out.

Step-by-Step Solution:
Step 1: Note that the focus is on clean water of the Ganga being supplied to domestic areas via postal services. Step 2: Identify that "Gangajal" is the common term for holy water from the Ganga. Step 3: Examine option A, "Gangajal Delivery Scheme", which directly mentions both Gangajal and delivery. Step 4: Compare it with Mission Bhagiratha, which you may recall is a drinking water grid scheme in Telangana, not a postal delivery scheme. Step 5: Recognise that the other options relate to skills promotion, travel insurance or a broader cleaning programme, none of which match the description, and choose option A as correct.

Verification / Alternative check:
Reviewing major government schemes announced around the time this initiative started, you will find newspaper reports describing the postal department delivering Gangajal to people's homes under the "Gangajal Delivery Scheme". The reports highlight that bottled water from Haridwar and Rishikesh would be transported to Bihar and then distributed by India Post. This strong name and description match confirms that "Gangajal Delivery Scheme" is the right answer.

Why Other Options Are Wrong:
Mission Bhagiratha in Telangana is a state level drinking water supply project and does not involve postal delivery of Ganga water in Bihar.
The National Apprenticeship Promotion Scheme is related to skill development and incentives for employers to engage apprentices, not to religious water distribution.
Railway Travel Insurance is a scheme that provides optional insurance coverage to train passengers and has no connection with Gangajal.
Namami Gange is a flagship programme for cleaning and rejuvenating the river Ganga and improving river front infrastructure, not a targeted postal delivery scheme for holy water.

Common Pitfalls:
One common pitfall is to choose Namami Gange simply because it is the most famous Ganga related programme. However, the question is about delivery of holy water to homes via post offices, which is much narrower in scope. Another mistake is not paying attention to the word "Bihar" and "postal services", which point strongly toward a specialised scheme implemented by India Post. Careful reading of the description and matching with the function implied in the scheme name will help avoid these errors.

Final Answer:
The scheme launched by the Central Government in Bihar to deliver clean Ganga water through the postal department is called the "Gangajal Delivery Scheme".
