Solution

## The correct option is A II onlySpeed is a scalar quantity that only number and velocity is a vector which means having magnitude and direction both. In order to have constant velocity the speed needs to be constant. Whereas a body can have constant speed with changing direction (velocity).When car going roundabout is the perfect example of this situation.
