Solution
The correct option is C leg-haemoglobin
Nitrogen-fixing bacteria like Rhizobium forms root nodules while in symbiotic association with legumenous plants.
When cut, the central portion of the nodules is red or pink. This is due to the presence of haemoglobin-like pigment called leg-haemoglobin present in the nodules.
These pigments act as oxygen scavengers by binding to any oxygen present in the nodules. Oxygen decreases the activity of nitrogenase enzyme. Leghaemoglobin keeps the nitrogenase free from oxygen by binding to the oxygen molecules entering the nodule.
