In an ideal Otto cycle, air is compressed from $1\mathrm{.}20k\frac{g}{m^3}$ and $2\mathrm{.}2$ L to $0\mathrm{.}26$ L $,$ and the net work output of the cycle is $440k\frac{J}{k}g.$ The mean effective pressure $($MEP$)$ for this cycle is

$($a$)544$ kPa

$($b$)599$ kPa

$($c$)528$ kPa

$($d$)416$ kPa

$($e$)367$ kPa
