\[{{K}_{1}},{{K}_{2}}\] and \[{{K}_{3}}\] are the equilibrium constants of the following reactions (I), (II) and (III) respectively:(I) \[{{N}_{2}}+2{{O}_{2}}\rightleftharpoons 2N{{O}_{2}}\](II) \[2N{{O}_{2}}\rightleftharpoons {{N}_{2}}+2{{O}_{2}}\](III) \[N{{O}_{2}}\rightleftharpoons \frac{1}{2}{{N}_{2}}+{{O}_{2}}\]The correct relation from the following is

• A. \[{{K}_{1}}=\frac{1}{{{K}_{2}}}=\frac{1}{{{K}_{3}}}\]        
• B. \[{{K}_{1}}=\frac{1}{{{K}_{2}}}=\frac{1}{{{({{K}_{3}})}^{2}}}\]
• C. \[{{K}_{1}}=\sqrt{{{K}_{2}}}={{K}_{3}}\]    
• D. \[{{K}_{1}}=\frac{1}{{{K}_{2}}}={{K}_{3}}\]
