The correct answer is A. Engine : Fuel.
Liquor is a drink that can cause intoxication, which is a state of being affected by alcohol. Similarly, an engine needs fuel to run. Without fuel, an engine will not work.
The other options do not have the same relationship. Medicine is used to cure illness, but it does not necessarily cause intoxication. A bottle is a container for liquids, but it does not need a cork to work. Whisky is a type of liquor, but it is not the only type of liquor that can cause intoxication.
Here are some additional details about each option:
- Option B: Medicine : Cure. Medicine is used to treat or prevent illness. A cure is a treatment that completely eliminates an illness.
- Option C: Bottle : Cork. A bottle is a container for liquids. A cork is a stopper that is used to seal a bottle.
- Option D: Whisky : Alcoholic. Whisky is a type of liquor. Liquor is an alcoholic beverage.
