Hi,
Found this article on AWS Direct Connect. Think it’s related to the answer. Awaiting for Whizlabs to come out with answer and explanation.

Thanks

Correct Answer is B

AWS uses the most specific route in your route table that matches the traffic to determine how to route the traffic (longest prefix match). Hence the one that matches this is Site B.

Option A,C and D are all incorrect since the shortest prefix would be chosen.

For more information on route table priority, please visit the below url

So, The correct answer is Site B
