Arrange the following isothermal processes in order of the magnitude of the work $(w)$ involved between states $1$ and $2$.
$A$. Expansion in single stage $(w_A)$
$B$. Expansion in multi stages $(w_B)$
$C$. Compression in single stage $(w_C)$
$D$. Compression in multi stages $(w_D)$

    $|w_B| > |w_A| > |w_C| > |w_D|$
  • B
    $|w_C| > |w_D| > |w_A| > |w_B|$
  • C
    $|w_C| > |w_D| > |w_B| > |w_A|$
  • D
    $|w_B| > |w_A| > |w_D| > |w_C|$
