Match the exact source IP address
Match IP addresses 10.1.1.1 through 10.1.1.4 with one access-list command without matching other IP addresses
Match all IP addresses in Barney’s subnet with one access-list command without matching other IP addresses
Match only the packet’s destination IP address
Access-list 101 permit tcp host 10.1.1.1 172.16.5.0 0.0.0.255 eq www
Access-list 1951 permit ip host 10.1.1.1 172.16.5.0 0.0.0.255 eq www
Access-list 2523 permit tcp any eq www 172.16.5.0 0.0.0.255
Access-list 2523 permit tcp 172.16.5.0 0.0.0.255 eq www 172.16.5.0 0.0.0.255

None of the other answers are correct.
Delete the entire ACL and reconﬁgure the three ACL statements that should remain in the ACL.
Delete one line from the ACL using the no access-list... command.
Delete one line from the ACL by entering ACL conﬁguration mode for the ACL and then deleting only the second line based on its sequence number.
Delete the last three lines from the ACL from ACL conﬁguration mode, and then add the last two statements back into the ACL.
Perform all ﬁltering on output if at all possible.
Put more-general statements early in the ACL.
Filter packets as close to the source as possible.
Order the ACL commands based on the source IP addresses, lowest to highest, to improve performance.
