Four pairs of words are given out of which the words in three pairs have a certain common relationship. Choose the odd pair of words.

Correct option is A

​$$\text{Given word pairs:} \\\text{1. Spoon : Stir} \quad \text{(A spoon is used to stir, but the action is performed by the user)} \\[6pt]\text{2. Spade : Dig} \quad \text{(A spade is used to dig, a direct action performed by the spade)} \\[6pt]\text{3. Gun : Shoot} \quad \text{(A gun is used to shoot, a direct action performed by the gun)} \\[6pt]\text{4. Pen : Write} \quad \text{(A pen is used to write, a direct action performed by the pen)} \\[6pt]\text{Common relationship:} \\\text{In pairs (B), (C), and (D), the object directly performs the action.} \\\text{In pair (A), the spoon is used to stir, but stirring is done by the person, not the spoon.} \\[8pt]\text{Thus, the odd pair is } \boxed{\text{Spoon : Stir}}.$$​​
