Which statement about using EtherChannel on Cisco IOS switches is true?

A.
A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel.
The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

B.
A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel.
The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 8 Gbps only for Gigabit EtherChannel.

C.
A switch can support up to eight compatibly configured Ethernet interfaces in an EtherChannel.
The EtherChannel provides full-duplex bandwidth up to 800 Mbps only for Fast EtherChannel or 16 Gbps only for Gigabit EtherChannel.

D.
A switch can support up to 10 compatibly configured Ethernet interfaces in an EtherChannel.
The EtherChannel provides full-duplex bandwidth up to 1000 Mbps only for Fast EtherChannel or 10 Gbps only for Gigabit EtherChannel.

Explanation:
An EtherChannel consists of individual Fast Ethernet or Gigabit Ethernet links bundled into a single logical link. The EtherChannel provides full-duplex bandwidth up
to 800 Mbps (Fast EtherChannel) or 8 Gbps (Gigabit EtherChannel) between your switch and another switch or host. Each EtherChannel can consist of up to eight
compatibly configured Ethernet interfaces. All interfaces in each EtherChannel must be the same speed, and all must be configured as either Layer 2 or Layer 3
interfaces.
