Consider the following three statements about link state and distance vector routing protocols, for a large network with 500 network nodes and 4000 links.[S1] The computational overhead in link state protocols is higher than in distance vector protocols.[S2] A distance vector protocol (with split horizon) avoids persistent routing loops, but not a link state protocol.[S3] After a topology change, a link state protocol will converge faster than a distance vector protocol.Which one of the following is correct about S1, S2, and S3 ?

• A. S1, S2, and S3 are all true
• B. S1, S2, and S3 are all false
• C. S1 and S2 are true, but S3 is false
• D. S1 and S3 are true, but S2 is false
