(d)खडकळ जमिन, गाळण प्रक्रियेला आणि नॉनएरोबिक अपघटनाला उपयुक्त नाही. / Rocky soils are unsuitable for filtration and non-aerobic decomposition.
Statements (b) and (c) are incorrect because porous soil is indeed preferred for filtration, and organic acids do not necessarily decrease overall soil fertility inappropriately in all contexts.
