Answer 1

The correct answer is (d) In-situ technique

To explain I would say: In-situ technique refers to on-site treatment of soil contaminants, Nitrogenase is protected by complexing with a specific leg-hemoglobin protein known as conformational protection, acidification leads to decrease in pH, global warming leads to increase in temperature.
