Quantum numbers of an atom can be defined on the basis of Pauli's exclusion principle. The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins. This means if one is assigned an up-spin ( +1/2), the other must be down-spin (-1/2). Thus, the correct answer is option 'C'.

Explanation:
Pauli's Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers. The quantum numbers are defined as follows:
1. Principal Quantum Number (n): It defines the energy level or shell of an electron. It can have a value of 1, 2, 3, and so on.
2. Azimuthal Quantum Number (l): It defines the shape of the orbital. It can have values from 0 to n-1.
3. Magnetic Quantum Number (m): It defines the orientation of the orbital in space. It can have values from -l to +l.
4. Spin Quantum Number (s): It defines the spin of an electron. It can have two values, +1/2 and -1/2.
According to Pauli's Exclusion Principle, no two electrons in an atom can have the same set of four quantum numbers. This means that if two electrons occupy the same orbital, they must have opposite spins.
Therefore, the quantum numbers of an atom can be defined on the basis of Pauli's Exclusion Principle.
