Selected Answer: A
Correct answer “A” As per the RAML specification, the question mark denotes that a property is optional in this context. To illustrate, consider the example: ID?: integer. # optional property; equivalent to -> # ID: # type: integer # required: false Moreover, in question #94, a valid example is presented for the same type. It's worth noting that in that example, the ID and publisher lack a trailing question mark (?) as seen on the right.

The correct answer is A. CANNOT SEND "id?" or any kind of "?propName" like that. Also publisher and id are not required so no need to send them
