Automobile : Petrol ::____________:______________

Man : Food

The answer is Man : Food.

The analogy is source of energy. An automobile uses petrol as its source of energy, and a man uses food as his source of energy. The other options do not make sense in the context of the analogy.

Option 1: Plane : Propeller: While a plane uses a propeller for propulsion, this relationship is not directly analogous to the relationship between an automobile and petrol. A propeller is a component of a plane, not a fuel source.

Option 2: Ship : Hull – The hull is the body of the ship, but it doesn't serve the function of powering the ship.

Option 3: Tea : Garden: Tea is a product that can be grown in a garden, but this relationship is not about a necessary fuel or resource. A garden provides a place to grow tea, but it's not the essential element for tea's existence.
