Solution
The correct option is A Acceleration
A vector quantity is a quantity which has a magnitude as well as direction. Acceleration of a body has got both i.e. magnitude and direction. So if we say a car is speeding at the rate 20 meter per square second in southward direction, it represents a vector quantity. The acceleration comes in the picture when an object changes its direction, increases or decreases its velocity.
