Read the Assertion and Reason below and choose the correct option. — Atomic Structure Chemistry Question

💡 Solution & Explanation

Statement I is correct as the spin quantum number has two possible values, $+1/2$ and $-1/2$. Statement II is incorrect because the positive and negative signs represent the two opposite spin states (spin up and spin down) of the electron, not the positive and negative signs of the wave function itself. Therefore, correct answer is C.
