What is the correct IF statement for the cost using the following condition:

The cost is $$20$ if the order quantity is greater than $3000.$

The cost is $$25$ if the order quantity is between $2000$ and $3000.$

The cost is $$30$ if the order quantity is less than $2000.$

Assume that the cost and the order quantity are in B$9$ and B$5,$ respectively.

Question $2$ options:

$=$IF$($B$9>3000,30,$ if$($B$9>=2000,25,20))$

$=$IF$($B$5>3000,30,$ if$($B$5>=2000,25,20))$

$=$IF$($B$5<2000,30,$ if$($B$5<=3000,25,20))$

$=$IF$($B$9<2000,30,$ if$($B$9<=3000,25,20))$
