Final answer:
In the 8086 microprocessor, the coprocessor can be interfaced in both max mode and min mode, but it does not support pipelining.
Step-by-step explanation:
In the 8086 microprocessor, the coprocessor can be interfaced in both max mode and min mode, so option A and B are both true. Option C is also true, as I/O can be interfaced in both max mode and min mode. The statement that is not true is option D, as the 8086 microprocessor does not support pipelining.
