To answer this question, you need to understand the concept of castling in chess.
Option A) Hooking - This option is incorrect because "hooking" is not a valid move in chess.
Option B) Fishing - This option is incorrect because "fishing" is not a valid move in chess.
Option C) Castling - This option is correct because castling is a move in chess that involves the king and rook. It is a special move where the king moves two squares towards the rook, and the rook moves to the square next to the king. Castling can only be done under certain conditions: neither the king nor the rook involved in the move can have moved previously, there must be no pieces between the king and the rook, and the king cannot be in check or pass through squares that are attacked by enemy pieces.
Option D) Dwarfing - This option is incorrect because "dwarfing" is not a valid move in chess.
The correct answer is C) Castling. This option is correct because it describes the move that changes the positions of the king and rook and puts them side by side in chess.
