What are quarks?
Quarks are extremely small substances which join with each other by extremely strong forces and makeup neutrons and protons of the atom. They combine in a similar way that the protons and neutrons combine to form the nucleus of an atom.
Quarks are categorized in flavours and there are 6 different types of flavours of quarks. The flavours differ from each other on the basis of their charge and mass.
The six flavours of quarks are grouped as three pairs. These are up and down, charm and strange and top and bottom.
Quarks are defined as true elementary particles. They have no defined structure and cannot be subdivided into smaller particles.
Therefore, the correct option is A is yes, B is Yes and C is No.
