Option 4 : All I, II and III

Entropy is defined as the amount of heat energy in an object that is not available for conversion into mechanical energy for work and it is a scalar quantity.
Potential Difference is also a scalar quantity since it is defined as a certain amount of work done and work is another scalar quantity.
Density has only magnitude and no direction, hence, it is also a scalar quantity.
