Assertion: Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.
Reason: This principle is a result of the wave nature of electrons.
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.

The Pauli Exclusion Principle states that in an atom none of the two electrons can have the four quantum numbers of a similar set. This is because electrons are wave-like in nature and are described by wave functions that depend on these quantum numbers. Because the wave functions must be unique for each electron, no two electrons in an atom can have the same set of four quantum numbers. Therefore, both Assertion and Reason are correct, and Reason correctly explains the Assertion. Hence option A is the correct answer.
Option (B) is incorrect because it incorrectly states that the assertion is correct but the reason is incorrect. Both the assertion and reason are correct. Hence option B is incorrect.
Option (C) is incorrect because it incorrectly states that the assertion is incorrect but the reason is correct. The assertion is correct, and the reason is also correct. Hence option C is incorrect.
Option (D) is incorrect because it incorrectly states that both the assertion and reason are incorrect but both the assertion and reason are correct. Hence option D is incorrect
