hey im doing analogies... and i need help on some of them

Seatbelts : Cars::
a)filters:coffee machines
b)oven:stove
c)radio:sound waves
d)color:paper
e)bricks:contruction

and i thought A would fit into the seatbelts and cars but whats a sentence that i can use to show that they are similar?

Filters are necessary for coffee machines because they protect the finished coffee from the grounds. How are seatbelts necessary for cars?

seatbelts protects the person in the car?

Right. :-)

Yes, that's correct! Seatbelts are necessary for cars because they protect the people inside the car. They act as a safety measure in case of accidents or sudden stops, preventing passengers from being thrown forward or out of the vehicle. Just like how filters are necessary for coffee machines to protect the finished coffee, seatbelts are necessary for cars to protect the people inside. They both serve a similar purpose of ensuring safety and preventing any potential harm.
