Assertion (A): Organic-S is made available to plants under aerobic upland conditions by mineralization into sulphates by S-oxidizing bacteria such as Thiobacillus.
Reason (R): Mineralization of organic-S results in production of \(H^+\) ions leading to the acidification of soil.
In light of the above statements, choose the correct answer from the options given below.
