Final Answer :
D
Explanation :
Sequencer switches are mainly used when a repeatable operating pattern is required, which makes option D the best choice. While timers and time-delay functions can be achieved with sequencers, they are not the primary purpose of this type of switch. Similarly, counters are not directly related to sequencer switches.
