Solution
The correct option is B Zn
Khaira disease is a disease of rice which appear on the lower surface of the leaves, the grains are less and light in weight and on the lower leaves that are small brown colour spots. This disease is caused by the deficiency of zinc.Zinc catalyzes enzyme activity is an oxidation-reduction mechanism, therefore, the deficiency and this leads to the disease in plants.In the mechanism for auxin, synthesis zinc is also very necessary for its deficiency also messes up the synthesis of auxin.So, the correct option is 'Zn'
