Correct answer is (c) JEDEC

To elaborate: The maximum time interval between refresh cycle is standardized by JEDEC, Joint Electron Device Engineering Council which is an independent semiconductor engineering trade organization. This standardized JEDEC in DRAM is specified in the manufacturer’s chip specification.
