please help with the questions that are wrong in red. Thanks!!

Rex and Felix are the sole shareholders of Dogs and Cats Corporation (DCC). After several years of operations using the accrual method, they decided to liquidate the corporation and operate the business as a partnership. Rex and Felix hired a lawyer to draw up the legal papers to dissolve the corporation, but they need some tax advice from you, their trusted accountant. They are hoping you will find a way for them to liquidate the corporation while minimizing their total income tax liability. Rex has a tax basis in his shares of $60,000 and Felix has a tax basis in his shares of $30,000. DCC's tax accounting balance sheet at the date of liquidation is as follows: Adjusted Basis FMV $ 38,000 $ 38,000 18,000 18,000 18,000 36,000 42,000 28,000 19,000 38,000 9,000 72,000 $ 144,000 $230,000 $ 45,000 30,000 Assets Cash Accounts receivable Inventory Equipment Building Land Total assets Liabilities Accounts payable Mortgage payable- Building Mortgage payable- Land Total liabilities Shareholders' Equity Common stock-Rex (80%) Common stock- Felix (20%) Total shareholders equity 30,000 $ 105,000 $100,000 25,000 $125,000 Answer is complete but not entirely correct.
