Answer 1

Right choice is (a) Support for fixed-length subnetting by including the subnet mask in the routing message

The explanation is: OSPF provides support for variable-length sunbathing by including the subnet mask in the routing message. For fixed length subnets, there is no requirement for including the subnet mask in the routing message as there is just one subnet mask for all the subnets.
