Question

Bird : Fish : : Aeroplane :?
(a) Submarine (b) Boat
(c) Crocodile (d) Ship

Answer 1

Here it might be a little tricky because ship, submarine and boat are all possible answers. Crocodile cannot be an answer because aeroplane is non-living. But if you think closely, a fish is always under water except for short durations or under exceptional circumstances. This is best linked to a submarine which is meant to stay underwater.
