Classical physics is applicable to macroscopic world.

Complex technologies are making use of more rarefied physical concepts. Physics describes the things that are possible in the universe, and technology is eventually built to do work within that which has been discovered by physics. This interplay also works in reverse. Modern physicists are frequently making use of extremely high-tech machines and processes. For example, the Large Hadron Collider in Switzerland is the world's largest particle accelerator. It can be operated at higher energies than any previous one. It was built explicitly to perform experiments in particle physics.

Thus Physics and technology are very much related to each other. So statement B is not appropriate. Although the other three statements are very much correct and factful.

Thus option B is correct.

The principal thrust in physics is to unity all the fundamental forces into a single framework and reduce the no.of different theories to minimal no. of models which can describe a great number of a phenomenon. (a)

The reduction is breaking down of a complex system into simple constituent systems to so that laws of physics can be applied to these systems and we can understand the working of the complex system.

In dams,the gravitational potential energy of water is used to turn the turbines which generate electrical energy.

Normal force,tension force and Frictional force,all are macroscopic forces.

Electric generator was faradays law of electromagnetic induction,a changing magnetic flux gives rise to electric current.

Molecular and nuclear phenomenon come under microscopic domain.

Heliocentric theory is an astronomical model which was proposed by Polish astronomer Nicolaus Copernicus. In this theory, the sun is at the center of the solar system and all the planets and heavenly bodies revolve around it.
