Concept:The conjunction 'whereas' is used to show a contrast between two related ideas.
Explanation:The two given sentences contrast the interests of Kavya and her sister.
Kavya is interested in reading books.
Her sister shows interest in outdoor games.
To combine them using 'whereas', we place the conjunction between the two contrasting clauses.
The correct sentence must clearly show their differing interests without changing the meaning.
Option A states: "Kavya is interested in reading books whereas her sister's interest is outdoor games."
This correctly preserves both original ideas and uses 'whereas' to highlight the contrast.
Option B changes the meaning by saying the sister is not interested in reading, which is not the original information.
Option C has a grammatical error: "Kavya is interested is reading".
Option D changes "outdoor games" to "to play outside", which is not exact.
Therefore, option A is the only grammatically correct and accurate combination.
Answer:Option A: Kavya is interested in reading books whereas her sister's interest is outdoor games.
