Bose-Einstein condensates
B
Plasma
C
Gas
D
Solid
Explanation: 

Detailed explanation-1: -Bose-Einstein Condensate: What Is The ‘Fifth State of Matter’? Sometimes referred to as the ‘fifth state of matter’, a Bose-Einstein Condensate is a state of matter created when particles, called bosons, are cooled to near absolute zero (-273.15 degrees Celsius, or -460 degrees Fahrenheit).

Detailed explanation-2: -There are four states of matter common in everyday life - gases, liquids, solids, and plasmas. However, there is also a fifth state of matter - Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago.

Detailed explanation-3: -The fifth state of matter Called a Bose-Einstein condensate (BEC), the unique state of matter was first achieved by scientists more than 25 years ago. The BEC is known to have extraordinary properties which are totally unlike solids, liquids, gases and plasmas.

Detailed explanation-4: -Bose-Einstein condensates (BECs) – the existence of which was predicted by Albert Einstein and Indian mathematician Satyendra Nath Bose almost a century ago – are formed when atoms of certain elements are cooled to near absolute zero (0 Kelvin, minus 273.15 Celsius).

Detailed explanation-5: -This chilly substance was initially theorised by Albert Einstein and Satyendra Nath Bose in the early 1920s as the fifth state of matter, following solids, liquids, gases and plasma. It is a supercooled gas that no longer behaves as individual atoms and particles, but rather an entity in a single quantum state.
