If the work function for a certain metal is \[3.2\times {{10}^{-19}}\]joule and it is illuminated with light of frequency \[8\times {{10}^{14}}\]Hz. The maximum kinetic energy of the photo-electrons would be [MP PET 1993]

• A.            \[2.1\times {{10}^{-19}}J\]     
• B.            \[8.5\times {{10}^{-19}}J\]
• C.            \[5.3\times {{10}^{-19}}J\]     
• D.            \[3.2\times {{10}^{-19}}J\] \[(h=6.63\times {{10}^{-34}}Js)\]
