Answer: Option 'B' is correct.
Explanation:
Since we have given that
In case of Alpha:
Number of oranges = 18
Number of apples = 9
In case of Beta :
Number of oranges = 16
Number of apples = 4
We need to find the opportunity cost of producing 1 orange for Alpha and Beta.
Opportunity cost for Alpha is given by
![\frac{\text{number of sacrificing units}}{\text{Number of gaining units}}\\\\=(18)/(9)=2](https://img.qammunity.org/2020/formulas/mathematics/high-school/56mhfa3i2k5qscojiyu7a2fufr80uxvrv4.png)
Opportunity cost for Beta is given by
![(16)/(4)=4](https://img.qammunity.org/2020/formulas/mathematics/high-school/4evikjgp18iopgv1hmhun5g1fthstu4ow1.png)
Hence, Opportunity cost for producing 1 orange for Alpha and Beta are 9 apples and 4 apples respectively.
Hence, Option 'B' is correct.
