B is incorrect... as the primary address of an interface is always the lowest numerical if no primary is specified. If two or more candidate primaries are specified, then the lowest numerical is selected as the primary.

Authentication for OSPF is configured under the "protocol ospf area <areaid> interface <interfaceid> authentication ...", so you can figure that one out from that hint.

sparse-dense. RPs are not used in dense mode.

Not a realm I delve into much... so someone else will have to answer this one for you.
