Correct Option A 

Both assertion and reason are correct and are related. As the number of oxygen atoms increases, the electronegativity of the molecule increases, leading to increased polarity, and thus, increased acidity.  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.
