B Correct answer
Explanation

The Catalyst 1900 series switches use fragment-free switching as the default mode. Fragment-free reads the first 64 bytes of the frame to detect collisions before forwarding, balancing between cut-through (faster but more errors) and store-and-forward (slower but error-checking entire frame). Full duplex (D) is a transmission mode, not a switching mode.
