When new, a good helmet should fit:

Answer: A — Snugly

A good helmet should fit snugly when new for several reasons. A snug fit ensures that the helmet stays securely in place during a ride, reducing the risk of it shifting or coming off during a potential crash. This close fit also helps to absorb and distribute impact energy more effectively in the event of an accident, providing better protection for the rider's head. Additionally, a snug fit prevents the helmet from moving around or causing distractions while riding, contributing to overall safety and comfort.
