The long run will see the supply curve of a completive firm changing to the b. portion of the marginal-cost curve that lies above the average-total-cost curve.
<h3>What is the long-run supply curve in a perfect competition?</h3>
In a perfect competition, a company will only produce goods and services at a level where the marginal cost curve is above the average total cost in the long run.
This means that the supply curve will be the marginal cost curve but only the portion of this curve that is above the long-run average total cost curve.
The reason for this is that in the long-run., all the costs in a perfectly competitive firm are considered variable and so they can afford to avoid supply mishaps in the short term.
In conclusion, option B is correct.

Answer:
Beta = 0.62
Explanation:
<em>The capital pricing model establishes the relationship between expected return from a stock and its systematic risk . The systematic risk is that which affects all players (businesses and firms) in the entire market, such risks are occassioned by changes in interest rate, exchange rate e.t.c</em>
<em>According to the model , the expected return is computed as follows</em>
E(r) = Rf + β(Rm-Rf)
Rf- risk -free rate, Rm-Rf - market premium
E(r) = 12.2%, Rm-Rf = 10, β- ?
12.2 = 6% + β× 10
10β = 12.2 -6
β= (12.2-6)/10
= 0.62
