Assertion: Spin quantum number can have the value +1/2 or -1/2. Reason

1.	Assertion: Spin quantum number can have the value +1/2 or -1/2. Reason:(+) sign here signifies the wave function.A. If both assertion and reason are true and the reason is the correct explanation of the assertionB. If both assertion and reason are true but reason is not the correct explanation of the assertionC. If assertion is true but reason is falseD. If the assertion and reason both are false
Answer» Correct Answer - C Assertion is true but reason is false. Spin angular momentum of the electron, a vector quantity, can have two orientations (represented by + and - sign) relative to a chosen axis. These two orientation are distinguished by the spin quantum number `m_s` equals to `+1/2` or `-1/2`.These are called the two spin states of the electron and are normally represented by the two arrows `uarr` (spin up) and `darr` (spin down ) respectively.
