The correct answer is option 2, S.N. Bose. The name "Boson" is associated with the Indian physicist Satyendra Nath Bose, also known as S.N. Bose. He was a pioneer in the field of quantum mechanics and statistical physics.

In the early 20th century, Bose collaborated with Albert Einstein to develop a theory known as Bose-Einstein statistics. This theory describes the statistical behavior of particles that have integer spin, such as photons and certain types of elementary particles.

Bose`s work provided a foundation for understanding the behavior of particles at very low temperatures, where they can form a unique state of matter called a Bose-Einstein condensate. This state was later experimentally observed in 1995, confirming Bose`s theoretical predictions.

Although Albert Einstein collaborated with Bose on the statistical mechanics of these particles, the term "Boson" specifically honors S.N. Bose`s contribution to this field of research. It is worth noting that the terms "Bose" and "Boson" are often used interchangeably when referring to particles that obey Bose-Einstein statistics.
