which of the following is true about EIGRP for IPv6 on R1 after this configuration has been pasted into R1?

Router R1 currently has no configuration related to IPv6 or IPv4. The following configuration
exists in a planning document intended to be used to copy/paste into
Router R1 to enable EIGRP for IPv6 on interfaces F0/0 and S0/0/0. No other related
configuration exists. Assuming F0/0 and S0/0/0 reach an up/up state, which of the following
is true about EIGRP for IPv6 on R1 after this configuration has been pasted into R1?
ipv6 router eigrp 1
ipv6 unicast-routing
interface f0/0

ipv6 address 2000::1/64
ipv6 eigrp 1
interface s0/0/0
ipv6 address 2001::/64 eui-64
ipv6 eigrp 1

A.
EIGRP works on F0/0 and S0/0/0 without further configuration.

B.
EIGRP works with the addition of one command: a no shutdown command in EIGRP
router configuration modE.

C.
EIGRP works with the addition of one command: an eigrp router-id command in EIGRP
router configuration modE.

D.
EIGRP for IPv6 needs at least two more configuration commands before it works on R1.

Explanation:
Because the question states that no IPv4 configuration exists, EIGRP for IPv6 cannot derive
a 32-bit EIGRP router ID. Before EIGRP will work, R1 needs to define an EIGRP router ID
(using the eigrp router-id command) and enable EIGRP using the no shutdown router
subcommand.
