Answer:
The corporation must recognize a $10,000 loss.
Explanation:
The last activity that a corporation must perform upon liquidation is to distribute property, assets or cash to its shareholders. The adjusted basis for any property or assets handed out in a complete liquidation is the fair market value of the property or assets.
In this case, the corporation's property had a basis of $40,000 but a fair market value of $30,000, so the distribution was done using the fair market value of $30,000.
