Final answer:
b) Stock liquidity
Alyssa's related benefit of a corporation when selling her Radio Shack stock is stock liquidity, which allows for easy selling of shares and limits liability to the investment amount.
Step-by-step explanation:
When Alyssa decides to sell her Radio Shack stock, the related benefit of a corporation she would discover is stock liquidity. The concept of stock liquidity pertains to the ability of shareholders to easily buy or sell shares without greatly affecting the share price. Corporations provide the advantage of being able to raise capital by selling stock, which in turn allows for easier transfer of ownership through the sale of these stocks. Unlike a sole proprietorship, which involves unlimited liability, a corporation limits a shareholder's liability to the amount they have invested in the corporation. This encourages investment and provides a way to finance company growth.
