 As we learned that

1) Scalar Quantity

The quantities having magnitude only are known as a scalar quantity.

Examples-Distance, time, work, energy, etc

2) Vector Quantity

The quantities having both directions as well as magnitude are known as vector quantities.

Examples - Displacement, force, velocity, acceleration, momentum, etc.

In option 1-(Time, Work)- Both are scalar quantities. So it is incorrect

In option 2-(Force, Current)- Force is a vector quantity. So it is incorrect

In option 3- (Length, Mass)- Both are scalar quantities. So it is incorrect

In opt. 4- (Speed, Velocity)-  Speed is scalar quantity and Velocity is a vector quantity. So it is the correct option.
