Which sequence represents the correct order of common fiber optic connectors from left to right?

Explanation:
Common fiber optic connectors are identified by two key features: ferrule size and locking mechanism. LC is the small-form-factor with a 1.25 mm ferrule, ST is a bayonet-style (twist-lock) connector, SC is a snap-on type with a 2.5 mm ferrule, and FC is a screw-on type with a 2.5 mm ferrule. The sequence described—ST, SC, LC, LC, FC—follows a typical left-to-right listing used in many references that moves from the older, larger-diameter designs toward the compact LC form-factor in the middle and ends with the screw-on FC. This arrangement helps you quickly identify each connector by its distinctive shape and locking style: bayonet for ST, snap-on for SC, tiny form-factor for LC, and a screw-thread for FC.
