B. Expectations of a recession that will reduce economy-wide corporate profits will likely cause the value of Edison's shares to decline

The price of the stock changes only because of the changes in the profitability of the firm. If the company is earning lower profits then the prices of the stock will fall and vice versa. So the option A is correct because increase in profitability increases the value of the shares.

So the main thing here is the profitability of the firm which is affected by the recession in the economy because during the recession period the profitability of the firm decreases and so the value of the stock decreases. So the option B is correct
