Note

For the "Client ORO" column: a "Yes" for an option means that
the client includes this option code in the Option Request
option (see Section 21.7 of [RFC-ietf-dhc-rfc8415bis-12]) 
if it desires that configuration information; a "No" means 
that the option MUST NOT be included (and servers SHOULD 
silently ignore that option code if it appears in a client's 
Option Request option).
