Consider the following pairs : Vitamin Deficiency disease 1. Vitamin C : Scurvy 2. Vitamin D : Rickets 3. Vitamin E : Night blindness Which of the pairs given above is/are correctly matched?

Explicitly lists scurvy as an example of a deficiency disease studied in the curriculum, linking the disease category to nutrient lack.

A student could infer that specific nutrient deficiencies map to specific named diseases and therefore seek which vitamin is linked to scurvy.

Defines 'deficiency diseases' as diseases caused by lack of specific nutrients in the diet and groups them as non-communicable.

Using this rule, a student would treat scurvy as likely caused by lack of some dietary nutrient and look up which vitamin corresponds to scurvy.

Gives a clear example of a specific nutrient (iodine) deficiency causing a named disease (goitre), illustrating the pattern 'missing nutrient → specific disease'.

By analogy, a student can apply the same mapping to vitamins: identify the vitamin whose absence historically causes scurvy.

Notes that deficiencies of particular vitamins/minerals (iron, vitamin B12) cause specific health problems, reinforcing that different micronutrient deficits produce distinct diseases.

A student could use this pattern to narrow that scurvy should correspond to the absence of a particular vitamin and then check standard references for which one.

States that food provides vitamins as essential nutrients for growth, establishing that vitamins are the class of nutrients relevant to deficiency diseases.

Knowing scurvy is a deficiency disease involving vitamins, a student can focus on identifying which vitamin (from the class named) is linked to scurvy using common external sources.
