Explanation:
The reason why option “B” is not valid is as follows;

In complex Ethernet topologies, traffic imbalances occur due to increased traffic flow, and load balancing becomes challenging for some of the following reasons:
Incorrect load balancing by aggregate next hops
Incorrect packet hash computation
Insufficient variance in the packet flow
Incorrect pattern selection
As a result of traffic imbalance, the load is not well distributed causing congestion in certain links, whereas some other links are not efficiently utilized.
