In India, the 'Mission Indradhanush' campaign is associated with which key social objective?

Introduction / Context:
Mission Indradhanush is a major public health initiative launched by the Government of India to improve immunization coverage. This question tests whether the candidate can correctly link the campaign with its primary social objective, among other health related goals that may sound similar but are separate schemes.

Given Data / Assumptions:

• The campaign is called Mission Indradhanush.
• The options list different social and health objectives, such as nutrition, diabetes awareness, blindness eradication, and child vaccination.
• We assume knowledge of key government schemes and their core purposes.

Concept / Approach:
Mission Indradhanush is specifically aimed at increasing immunization coverage by ensuring that children and pregnant women receive all recommended vaccines. It does not directly provide nutrition, focus on diabetes awareness, or target blindness as its main goal. Therefore, associating Mission Indradhanush with vaccination of children is the correct approach.

Step-by-Step Solution:
Step 1: Recall that Mission Indradhanush uses the imagery of a rainbow to represent full coverage of vaccines against various diseases.Step 2: Remember that the campaign targets children who are partially vaccinated or not vaccinated at all, with special drives in high risk areas.Step 3: Compare this with the options and note that vaccination of children fits perfectly with the known objective of the mission.Step 4: Confirm that the other options correspond to different health initiatives or general goals rather than to this specific mission.

Verification / Alternative check:
Health ministry documents and public information campaigns describe Mission Indradhanush as focused on achieving higher levels of full immunization coverage. The scheme outlines specific vaccines and target groups, especially children under a certain age and pregnant women. There is no reference to it being a nutrition campaign, a diabetes awareness programme, or a blindness eradication mission. This confirms that vaccination of children is the correct association.

Why Other Options Are Wrong:
Nutrition to pregnant women: Important but covered under other schemes, not the central purpose of Mission Indradhanush.
Awareness of diabetes: Diabetes awareness programmes exist, but they are not titled Mission Indradhanush.
Eradication of blindness: Programmes for eye health and blindness control have their own names and frameworks and are separate from this immunization mission.

Common Pitfalls:
Since several health schemes focus on mothers and children, candidates may mix them up if they only remember that a scheme is about public health. Some may wrongly assume that Indradhanush relates to nutrition or general child welfare. To avoid this, it is useful to connect the word Indradhanush with multiple vaccines, like the colours of a rainbow, and memorise that its main focus is immunization and vaccination drives.

Final Answer:
Mission Indradhanush in India is associated with the vaccination of children.
