Show answer & explanation
Correct answer: D
The correct answer is Option D (READY). In the 8085, the READY input is used to synchronize the processor with slower memory or slower I/O devices. If the addressed device is not ready, READY is held low and the processor inserts wait states. Once READY goes high, the 8085 completes the bus cycle. INTR is for interrupts, RESET IN resets the processor, and HOLD is used for DMA bus request; none of these are meant for slow-memory synchronization.
