Why each option

SDN separates the control and data planes, enabling programmability and centralized automation that reduces both capital and operational costs while accelerating innovation through open APIs.

Aprovides additional redundancy

Redundancy is an architectural design choice independent of SDN - SDN does not inherently add physical or logical redundancy to the network.

Bdecentralized management

SDN moves toward centralized management via a controller, which is the opposite of decentralized management.

Creduced latency

SDN does not inherently reduce latency - in some cases the controller round-trip can introduce additional delay for flow setup.

Denables innovationCorrect

SDN exposes network programmability through open APIs and abstracts hardware, allowing developers and operators to rapidly prototype and deploy new network services and applications that traditional hardware-locked networking cannot support.

Ereduction of OpEx/CapExCorrect

By centralizing control and enabling automation, SDN reduces OpEx through lower manual configuration overhead and reduces CapEx by allowing commodity hardware to replace expensive proprietary appliances.

Fmeets high traffic demands

Meeting high traffic demands is a function of bandwidth provisioning and QoS, not a primary benefit of SDN architecture.
