The question is an analogy problem, which means we need to find the relationship between the first pair of words and then apply the same relationship to the second pair.
Identify the relationship in the first pair: The first pair given is "Brinjal : Vegetable". Here, Brinjal is a type of vegetable. This establishes a relationship of classification; Brinjal is classified under vegetables.
Apply the same relationship to the second pair: We need to find out what Orange is classified as. The options provided are Fruit, Stem, Leaf, and Root.
Examine the options:
Fruit: Orange is a type of fruit. This matches the structure of the relationship in the first pair (Brinjal : Vegetable).
Stem, Leaf, Root: These options are parts of plants but do not reflect what an Orange is classified as.
Conclusion: Based on the classification, the correct answer is "Fruit" because just as Brinjal is classified as a vegetable, Orange is classified as a fruit.
