Assertion: As the `pH` of water decreases , the solubility of metal ions increases.
Reason: Water having `pH lt 5.5` is not suitable for drinking purposes.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true and the reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.
