Refer to the exhibit. In this network，R1 is configured not to perform autosummarization within EIGRP. What routes will R3 learn from R2 through EIGRP？（）

• A、172.30.1.0/24 and 10.1.2.0/24；EIGRP only performs autosummarization at the edge between two major networks
• B、172.30.0.0/16 and 10.1.2.0/24；R2 will perform autosummarization，although R1 will not
• C、Since R2 is configured without autosummarization，it will not propagate the 172.30.1.0/24 route
• D、172.30.0.0/8 and 10.0.0.0/8
