Assuming we implement our Quicksort algorithm to always choose the last element in a group as the pivot and do not reorder the elements when placing them in a group, which of the following inputs would be a worst$-$case input when sorting in ascending order $($requiring the most steps to sort$)?$

Group of answer choices

$[5,6,7,8,1,2,3,4]$

$[2,4,6,8,1,3,7,5]$

$[1,2,3,4,5,6,7,8]$

$[5,4,7,2,8,1,3,6]$
