The Correct Option is B
Solution and Explanation
The 8279 programmable keyboard/display interface requires a slower clock cycle compared to the 8086 microprocessor operating at 8 MHz. To synchronize the data transfer between the two devices, wait states are introduced. For an 8 MHz clock, the calculation for the number of wait states shows that 3 wait states are needed for proper interfacing.
