The wavelength of maximum energy released during an atomic explosion was \[2.93\times {{10}^{-10}}\] m. Given that Wien's constant is \[2.93\times {{10}^{-3}}\] m-K, the maximum temperature attained must be of the order of

• A. \[{{10}^{-7}}K\]        
• B. \[{{10}^{7}}K\]
• C. \[{{10}^{-}}^{13}K\]
• D. \[5.86\times {{10}^{7}}K\]
