Question 5
Which of the following groups contains vector quantities only?
The right answer is the one marked above.
Displacement, velocity, acceleration. Stating any of these three in full needs a direction as well as a magnitude, which is exactly what makes a quantity a vector.
Distance, speed, mass and time are scalar quantities — they have a magnitude only. "160 m east" is a displacement; plain "160 m" is a distance. Weight is a vector too, because it is a force and so has a direction.
