Refer to the exhibit.The actual speed of the serial links between R2 and R3 are 256 kb/s and 512k b/s respectively. When configuring EIGRP on routers R2 and R3, the network administrator configured the bandwidth of both serial interfaces to 512 kb/s. What will be the effect?（）

• A、EIGRP will overutilize the 512 kb/s link.
• B、The interface "delay" value used in the EIGRP metric calculation will be inaccurate on the 256k b/s serial interface.
• C、The amount of bandwidth used for EIGRP routing protocol traffic on the 256 kb/s link can become excessive.
• D、EIGRP can load balance between the two serial links only if the variance is set to 2 or higher.
• E、Unequal cost load balancing will be disabled.
