Right choice is (d) refresh cycle

The best explanation: The data storage in RAM which is capacitance (reverse-biased diode) may have a leakage current that tends to discharge the capacitor giving rise to possibility of data loss. To avoid this, the data must be refreshed after a fixed time interval regularly.
