Hint: It is known to us that the spin is one of the intrinsic properties of angular momentum which is carried by their constituent particles and atomic nuclei. Spin is also a type of angular momentum. And the other type is known as orbital angular momentum.
Complete Step by step answer: The spin angular momentum is the angular momentum which is created by its spinning of electrons. The spinning of electrons behaves like a tiny bar magnet. This fact was beautifully demonstrated by the Stern-Gerlach experiment.
Electrons are very small in size and they are present outside the nucleus in certain orbits. Electrons are also negligible in weight; Electrons are negatively charged. Neutron present inside the atomic nucleus. they have no charge i.e. they are neutral in charge. While protons are the only one which is the main reason behind electromagnetism.
Each particle i.e. electron, proton, neutron can spin in both directions i.e. electrons, neutron and pitons can rotate in clockwise or anticlockwise. So, each of these contains two spins clockwise and anticlockwise.
So we can say that the spin is the same in the electron, proton and neutron.
Hence, option (D) Equal sign, is the correct option.
Note: Mathematically, spin is explained on the basis of vectors for some particles like photons while spinors and disponers for different particles like electrons. Spinors have similar properties like vectors. Both have definite magnitude and rotations under charge. The spin quantum number is the fourth set of quantum numbers which explains about the spinning nature of electrons.
