What is quantum mechanics concerned with?

The behavior of subatomic particles
The behavior of stars and galaxies
The behavior of planets and their moons
The behavior of atoms and molecules

The correct answer is: The behavior of subatomic particles

Quantum mechanics is a branch of physics that deals with the behavior of subatomic particles. This includes particles such as electrons, photons, and protons. It explains how these particles behave and interact with each other. Option B is incorrect because quantum mechanics focuses on the micro world, not the macro world of stars and galaxies. Option C is incorrect because quantum mechanics does not deal with the behavior of larger objects like planets and moons. Option D is incorrect because while quantum mechanics does involve studying the behavior of atoms and molecules, it also includes the behavior of other subatomic particles. Therefore, the most accurate answer is A.
