b.It increases significantly, requiring much greater distance to stop
c.It becomes shorter because of the heavier weight
d.It is unaffected by speed

Heavier vehicles and higher speeds both greatly increase the distance needed to stop. A loaded truck traveling at highway speed needs far more room than a car. Drivers must increase following distance and plan stops well ahead.
