Of the four listed the vacuum cleaner is the closest even though it does not have a heating element and it sucks rather than blows.Which appliance below is most like a hair dryer?
A hair dryer has a small blower and a large resistance heating element.


None of your choices has any heating elements, and only the vacuum has a blower.
As they are both basically air pumps





the answer is :- 2.vacuum cleaners are MOST like.


The hairdryer also has a heater.





None of the other three options come close to being MOST like a hair dryer.
I would say a vacuum cleaner as it moves air like a hair dryer. However, I never see my daughter dry her hair with a vacuum, as it doesn't heat the air.
The most similar given the choices is... 2. vacuum cleaner.





( An air blower produces a vacuum on its inlet )
This question makes no sense to me. None of these things are anything like


a hair dryer except the ones with electrical plugs.
e. ---- One of those small counter-top convection ovens that has a fan and a heating element.
5.space heater
