Answer:
a.10GBaseSR
d.1000BaseSX
Step-by-step explanation:
In Computer Networking, The 1000BaseSX is a type of cabling standard used for deploying Gigabit Ethernet networks. The SX in 1000BaseSX denotes short, and it implies that it's for use with transmissions having short-wavelength over short runs of fiberoptic cabling in a Gigabit Ethernet networks.
The SR in 10GBaseSR denotes short-range, it is exclusively used for multi-mode fiberoptic medium that uses 850nm lasers having LC duplex connector and DDM with a maximum transmission distance of 300meters in a Gigabit Ethernet networks.
