Explanation:
OSPF supports the following two types of summarization.
To configure an ABR to summarize routes for a specific area before injecting them into a different area, use the
following syntax:
Router(config-router)#area area-id range address mask
To configure an ASBR to summarize extenal routes before injecting them into the OSPF domain, use the
following syntax:
Router(config-router)#summary-address adress mask

128 64 32 16 8 4 2 1
1 1 0 0 0 0 0
1 1 1 1 1 1 1

according to above, 1s kill 0s , we get only 64 + 32 = 96 for ip address

and subnetmask 128 + 64 + 32 = 224. The correct answer is ” A “
