How many times would the kinetic energy of a car increase if it’s velocity doubled

The only thing I can think of is coming from the basic expression for Kinetic Energy:
K=12mv2
that tells us that there is a direct proportionality between kinetic energy K and mass m, so that when you increase the mass of a moving object the kinetic energy will also increase, i.e.:
let us consider a car travelling at, say, 60kmh and having mass of 1000kg; when you have the same car travelling at the same velocity but now with double the mass (you are carrying your mates) the kinetic energy will double as well.

If its history of, then b) because a) implies only present day (now)
