Option A is the correct choice.

Step-by-step explanation:

We have been given that Mark earns $135 for selling a $1500 refrigerator.

Since proportions states that two fractions are equal , so we will use proportions to find the same commission rate with the listed price from our given choices.

We can set proportion for commission and listed price as:

Let us compare our given choices one by one.

A. $36 commission on a $400 dryer.

Upon simplifying our proportion we will get,

We can see that commission rates for both items are equal, therefore, option A is the correct choice.

B. $40 commission on a $500 dryer sale.

Upon simplifying our proportion we will get,

We can see that both commission rates are different, therefore, option B is not a correct choice.

C. $210 commission on $1400 oven sale.

Upon simplifying our proportion we will get,

Since the commission rates are different, therefore, option C is not a correct choice.

D.  $30 commission on a $600 freezer sale.

Upon simplifying our proportion we will get,

Since the commission rates are different, therefore, option D is not a correct choice.
