To evaluate the above expression, we use first convert it to reverse polish format using a shunting yard algorithm. Which of the following represent the correct order of reverse polish notation, when the above expression is evaluated?

$A) 1, 2, 2, 5, \times, /, 7, \times +$

$B) 1, 2, 2, 5, \times, \times, 7, / +$

$C)1, 2, \times, 2, 5, \times, 7, /, +$

$D) 1, 2, \times, 2, 5, /, 7, \times, +$
