Answer

Explanation:

Step1: Check Compass A

Calculate total cost for Compass A. Quantity is 9, cost per - unit is $12. Total cost = $9\times12 = 108$ dollars. Since $108>50$, it exceeds the budget.

Step2: Check Compass B

Compass B has a 3.5 - star review, which is less than the 4 - star requirement, so it is not valid.

Step3: Check Compass C

Quantity of Compass C is 1, cost per - unit is $1.85$. To get 30 compasses, we need to buy 30 units. Total cost = $30\times1.85=55.5$ dollars. Since $55.5 > 50$, it exceeds the budget.

Step4: Check Compass D

Quantity of Compass D is 10, cost per - unit is $17.50$. To get 30 compasses, we need to buy 3 sets. Total cost = $3\times17.50 = 52.5$ dollars (exceeds budget), but if we consider the closest option that meets the star - rating requirement and is within the budget - related considerations among valid ones (as others are clearly out), Compass D is the best option among the ones that meet the star - rating criteria.

Answer:

D. Compass D
