Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). In the light of the above statements, choose the correct answer from the options given below.

Assertion (A):Acidity in water with a pH level above 5 has a detrimental effect on aquatic life.

Reason (R):Water with a pH value between 5 and less than 7 is acidic in nature.

ABoth A and R are correct and R is the correct explanation of A

BBoth A and R are correct but R is not the correct explanation of A

CA is correct but R is not correct

DA is not correct but R is correct ✓ Correct

Correct answer: (D) A is not correct but R is correct

Explanation

Water becomes acidic and harmful to aquatic life below the neutral value of 7, so the assertion about a pH above 5 is wrong.

The assertion fails because moving above pH 5 toward neutral is not what damages aquatic life.

The reason is correct that water with a pH between 5 and just under 7 is acidic.

Anything below the neutral value of 7 counts as acidic in nature.

The assertion fails while the reason stands.

Acid rain can push lake pH low enough to kill fish eggs and young.
