There are three words which have something in common among themselves. Out of the four given alternatives choose the most appropriate description about these three words.
Knight : Rook : Bishop
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → These are chessmen
The knight, the rook (castle) and the bishop are three of the six kinds of pieces in chess, along with the king, the queen and the pawn. Each piece moves in its own way: the rook along straight lines, the bishop along diagonals and the knight in an L-shape.
Why the other options are incorrect
Option (1) These are missionaries — Incorrect. Missionaries are people sent to spread a religion; none of the three words means that.
Option (3) These are churchmen — Incorrect. A bishop is a senior priest of the church, but a knight and a rook are not churchmen.
Option (4) These are ranks of military — Incorrect. A knight was a mounted soldier of the Middle Ages and is now a title of honour, but rook and bishop are not military ranks.
