The correct answer is (A) Both assertion and reason are true and reason is the correct explanation of the assertion. Group 18 elements have high ionization energies because they have a complete outermost shell of electrons, which are strongly attracted to the nucleus and require a large amount of energy to remove. This also contributes to their stability and inertness. 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. Both the assertion and reason are correct. Hence option D is incorrect.
