The 144.20.0.0 network is not on router B so won't be
advertised. You can put it under the OSPF process but
it isn't going to do anything with that network
because it doesn't exist on that router at this time.
If it did, it would announce it.
If router B has a static route to 144.20.0.0 then you
can do a redist static under the ospf process to
redistribute the static routes on RouterB into OSPF.
Look at setting up distribute-lists and set the
metrics right to get proper results for what you are
looking to do.
