Select the most appropriate option to fill in the blank.
The children sat _________ the tables instead of the chairs.

Correct option is C

The correct option to fill in the blank is (c) on.
Explanation: We use "on" to indicate a position atop a surface. Children sitting on tables is grammatically correct and contextually makes sense.
Example: The book is on the table.
Explain why other options are incorrect:
· (a) above: Means higher than, but not in contact (ऊपर)
· (b) near: Means close to (पास में)
· (d) in: Used for enclosed spaces (के अंदर), which doesn’t suit “table”
