The answer is D. Minister.
A king, queen, bishop, and knight are all pieces in the game of chess. A minister is not a piece in chess.
A king is the most important piece in chess. It is the only piece that can move to any square on the board. The goal of the game is to checkmate the opponent’s king, which means to put it in a position where it cannot move without being captured.
A queen is the second most important piece in chess. It can move any number of squares in any direction.
A bishop is a piece that can move diagonally any number of squares.
A knight is a piece that can move two squares horizontally and one square vertically, or one square horizontally and two squares vertically.
A minister is not a piece in chess. It is a person who is responsible for a particular area of government or religious affairs.
