the correct answer is C and D because the overload command is on R2. . An overloaded routing device determines it is unable to handle any more OSPF transit traffic, which results in sending OSPF transit traffic to other routing devices.

Marius – u are correct
Overview
You can configure a local routing device running OSPF to appear to be overloaded, which allows the local routing device to participate in OSPF routing, but not for transit traffic. When configured, the transit interface metrics are set to the maximum value of 65535.
This example includes the following settings:
overload—Configures the local routing device so it appears to be overloaded. You might configure this if you want the routing device to participate in OSPF routing, but do not want it to be used for transit traffic, or you are performing maintenance on a routing device in a production network.

please pay attention : “An overloaded routing device determines it is unable to handle any more OSPF transit traffic, which results in sending OSPF transit traffic to other routing devices.” is not totally true. The overload means the router send all metric to be less prefered, not to be excluded.
if the only transit is the overloaded router, then it keep on routing packets.
