Which of the following will result from placing ACLs as close as possible to the source of the packets it is designed to filter?

A) There is less chance of packets being routed around the ACL.
B) The placement will save some bandwidth because the packets are dropped sooner.
C) The placement will diminish throughput because of the filtering effort.
D) Placing the ACL close to the source prevents collisions.
