The income statement shows a detailed picture of the transactions of all revenue and expenses. The income summary account then summarizes these figures in order to produce the statement of retained earnings. Both the income statement and income summary show the revenue and expenses of a company.
B) the other firm does not view the announcement as credible
Explanation:
The reason is that the other firm thinks that the announcing firm will make losses as it will not be able to sell the products in an imperfect market where both the firms have identical cost functions and knew all about the cost. So increasing the production when the demand is the same will decrease the price of the product and result in increased losses to the announcing company.
