Explanation
B is correct because OTN stands for Optical Transport Network, not "Open Transmission Network." OTN is an ITU-T standardized suite of protocols (G.709 and related standards) designed to transport various client signals over optical fiber infrastructure while providing operations, administration, maintenance, and provisioning (OAM&P) capabilities.
Option A is wrong because accepting "Open Transmission Network" would misidentify both key words - OTN is Optical (referring to fiber-optic technology), not "Open," and it is a Transport Network with a specific architectural meaning, not a generic "transmission" system.
Memory tip: Think of the "O" in OTN as standing for the light that travels through fiber - Optical = Optics = light. OTN is essentially the standardized "wrapper" that packages any type of traffic (Ethernet, SONET, etc.) for efficient, manageable transport across optical fiber networks.
