I picked C as the answer to this question but I am not sure?

The difference between production possibilities frontiers that are vowed out and those that are linear is that:

A)bowed out production possibilities frontiers illustrate tradeoffs, whereas linear production possibilities frontiers do not

B)bowed our production possibilities frontiers show increasing opportunity cost, whereas linear ones show constant opportunity cost

C)bowed out production possibilities frontiers are the result of perfectly shift able resources, whereas linear production possibilities frontiers are not

D)linear production possibilities frontiers illustrate real-world conditions more then bowed our production possibilities frontiers.

I would pick B.

To determine the correct answer to this multiple-choice question, you can analyze each option and eliminate the ones that are incorrect.

Option A states that bowed out production possibilities frontiers illustrate tradeoffs, while linear production possibilities frontiers do not. This is true because bowed out frontiers show the concept of trade-offs, where producing more of one good requires sacrificing the production of another good. Therefore, option A is a valid statement.

Option B states that bowed out production possibilities frontiers show increasing opportunity cost, while linear ones show constant opportunity cost. This is also a valid statement. Bowed out frontiers represent increasing opportunity costs because as you produce more of one good, you have to give up increasing amounts of the other good. Linear frontiers, on the other hand, represent constant opportunity costs where the tradeoff between the two goods remains constant.

Option C states that bowed out production possibilities frontiers are the result of perfectly shiftable resources, while linear production possibilities frontiers are not. This statement is incorrect because both types of frontiers can be the result of various factors, including resource availability, technology, and efficiency. Therefore, option C can be eliminated.

Option D states that linear production possibilities frontiers illustrate real-world conditions more than bowed out production possibilities frontiers. This statement is subjective and does not provide a definitive explanation of the difference between the two types of frontiers. Therefore, option D can also be eliminated.

By process of elimination, the correct answer is:

B) Bowed out production possibilities frontiers show increasing opportunity cost, whereas linear ones show constant opportunity cost.
