A fundamental physical quantity is one that cannot be defined in terms of other physical quantities. The SI system recognizes seven fundamental physical quantities: length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity.

Option A is correct because time is one of the seven fundamental physical quantities. It is defined as the duration between two events.

Option B is correct because mass is also one of the seven fundamental physical quantities. It is defined as the amount of matter in an object.

Option C is correct because length is another fundamental physical quantity. It is defined as the distance between two points in space.

Option D is incorrect because force is not a fundamental physical quantity. It can be defined in terms of the fundamental quantities of length, mass, and time, as force is the product of mass and acceleration. Therefore, force is a derived quantity rather than a fundamental one.

So, The correct answer is Opion 4.
