Your network contains two Active Directory forests named contoso.com and adatum.com. Each forest contains
one domain. A two-way forest trust exists between the forests.
The forests use the address spaces shown in the following table.
From a computer in the contoso.com domain, you can perform reverse lookups for the servers in the contoso.
com domain, but you cannot perform reverse lookups for the servers in the adatum.com domain.
From a computer in the adatum.com domain, you can perform reverse lookups for the servers in both domains.
You need to ensure that you can perform reverse lookups for the servers in the adatum.com domain from the
computers in the contoso.com domain.

It is not C, because we are talking about REVERSE lookup queries. Conditional forwarders are only for forward lookup zones (=domain name).
We need to create zone transfers/primary/stub zones in the DNS reverse lookup zone.
But any of the other answers are not true either… not 100% sure about delegation.
