Final answer:
The passenger should sit on the seat with you, and the mirror adjustments should be made by the person operating the motorcycle.
Step-by-step explanation:
When adjusting your mirrors to carry a passenger, the passenger should not be involved in adjusting the mirrors while you sit on the motorcycle. Instead, the mirror adjustments should be made by the person operating the motorcycle.
It is important for the passenger to sit on the seat with you or use designated passenger seating areas, depending on the type and design of the motorcycle.
Option d) None of the above is the correct answer because the passenger should not stand behind the motorcycle while it is in motion.
