Not to over-think the requirement, /18 aggregate will be good
enough, just give it 0.0.63.0, it will cover the first 64 subnets.
Otherwise, the differences between prefixes are complex enough to either not
to fit into one network statement, or there will be holes in the scope.
From the other point, if the task is to not to have any statement
starting with "network ... " at all when solving this task, you can use "ip
ospf X area 0" on the interface, where X is the OSPF process number. Minimum
number of network statements, can't be any less than 0.
#1 or #2 will really depend on the context, what is the point of the
task. Given that you have more than 1 valid solution, proctor will clarify
this for you. Not to mention, one of the solutions might be prohibited by
restrictions somewhere else in the scenario.
Cheers,
Adel.
