In which condition may plant roots face difficulty in absorbing nutrients from soil?
Answer and explanation
Correct answer: Soil pH is highly acidic or highly basic
Plant roots absorb mineral nutrients most effectively when soil conditions, including pH, are suitable. The governing concept is nutrient availability: extremely acidic or extremely basic soil can change the solubility of minerals and may damage roots, making absorption difficult. Thus option A is correct. Neutral soil is not automatically harmful, and the other choices are oversimplified rather than scientifically reliable conditions.
