For the first order reaction \[A\xrightarrow{{}}B+C\] is carried out at\[27{}^\circ C\]. If \[3.8\times {{10}^{-16}}\] % of the reactant molecules exists in the activated state, the \[{{E}_{4}}\](activation energy) of the reaction is:

• A. 12 kJ/mol         
• B. 831.4 kJ/mol
• C. 100 kJ/mol        
• D. 88.57 kJ/mol
