If the Reply Mode in the echo request is "Reply via an
IPv4 UDP packet with Router Alert", then the IP header MUST contain
the Router Alert IP Option of value 0x0 [RFC2113] for IPv4 or 69
[RFC7506] for IPv6.

It should say:

If the Reply Mode in the echo request is "Reply via an
IPv4/IPv6 UDP packet with Router Alert", then the IP header MUST contain
the Router Alert IP Option of value 0x0 [RFC2113] for IPv4 or 69
[RFC7506] for IPv6.

Notes:

The description of the Reply Mode recorded in the IANA "Reply Modes" sub-registry of the "Multiprotocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters" registry is "Reply via an IPv4/IPv6 UDP packet with Router Alert".
