The correct terms that represent a vector quantity and its respective unit from your options are:
b - force - Newton
d - weight - kilogram is incorrect because weight is also a vector quantity and should be expressed in Newtons, not kilograms.
- Option a (speed - meters per second) is incorrect since speed is a scalar quantity, not a vector.
- Option c (mass - kilogram) is also incorrect because mass is a scalar quantity, not a vector.
So, the only correct pair from the provided options is b (force - Newton).
