Dual Nature of Radiation and Matter

Question: 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

1) $2.1 \times {10^{ - 19}}J$

2) $8.5 \times {10^{ - 19}}J$

3) $5.3 \times {10^{ - 19}}J$

4) $3.2 \times {10^{ - 19}}J$ $(h = 6.63 \times {10^{ - 34}}Js)$
