The correct answer is option 2, Bose-Einstein Condensate (BEC) is the fifth state of matter.

To understand this, let`s first briefly go over the four classical states of matter.

1. Solid: In this state, particles are tightly packed together and have fixed positions. Solids have a definite shape and volume.

2. Liquid: Particles in a liquid are still close together, but they are not held in fixed positions. Liquids have a definite volume but take the shape of their container.

3. Gas: In the gas state, particles are far apart and move freely. Gases have neither a definite shape nor volume and can expand to fill any container.

4. Plasma: Plasma is the fourth state of matter, where some or all particles have been ionized. It is an electrically charged gas and is commonly found in stars and lightning.

Now coming to option 2, Bose-Einstein Condensate (BEC) is a unique state of matter that was first predicted by Satyendra Nath Bose and Albert Einstein in the 1920s. At extremely low temperatures close to absolute zero, certain types of particles called bosons can enter a state of matter known as BEC. In this state, a large
