Correct Answer - Option 4 : Gun : Cut
The logic followed is:
All except option (4), Second denotes the purpose for which the first is used.
Option 1 → Spanner : Grip
Spanner is basically used for the purpose to grip nut bolts.
Option 2 → Axe : Chop
Axe is used as a hand tool used for chopping, splitting, chipping, and piercing.
Option 3 → Spoon : Feed
Spoons are used primarily for eating liquid or semi-liquid foods, such as soup, stew or ice cream, and very small or powdery solid items which cannot be easily lifted with a fork, such as rice, sugar, cereals and green peas.
Option 4 → Gun : Cut
Gun is basically used for the purpose to shoot not to cut.
Thus this is odd from the rest of the options.
Hence, the correct answer is "Gun : Cut".
