Which description fits Frigates in the naval context?

Frigates are characterized historically as light and fast warships, typically armed with a moderate number of guns, traditionally ranging from 28 to 44. This description emphasizes their role as agile and versatile naval vessels that are designed for various missions, including protection of merchant shipping, reconnaissance, and escort duties. Their speed and maneuverability allow them to operate effectively in a range of maritime environments, fulfilling crucial roles in naval strategy.

In contrast to this, the other options either describe different types of naval vessels or mischaracterize what frigates represent. The largest warships would typically refer to ships like aircraft carriers or battleships, which serve very different purposes. Submarines with stealth capabilities are a completely different class focused on underwater warfare, and support vessels imply auxiliary roles that do not fully encapsulate the combat and operational functions of frigates.
