  1. router(config-line)# ip access-group 1 in
  2. router(config-line)# ip access-list 1 in
  3. router(config-line)# access-class 1 in
  4. router(config-line)# access-line 1 in
Explanation
Answer - C - To assign the access list to the Virtual Terminal Lines, you must use the router (config-line) # access-class 1 in.

Key Takeaway: To restrict incoming and outgoing connections between a particular vty and the addresses in an access list, use the access-class command in line configuration mode.
