B)AMI
C)VSES
D)B8ZS

Question

NRZ (Non-Return-to-Zero) codes have a simple structure and are ideal for digital magnetic recording due to their low frequency response characteristics. This makes them a common choice for magnetic storage devices like hard disk drives and magnetic tape drives. AMI (Alternate Mark Inversion) codes are also commonly used, but their voltage levels can cause issues with signal integrity and noise. VSES (Variable-Length Sub-Echo Signal) and B8ZS (Binary 8-Zero Substitution) codes have more complex structures and are typically used for long-distance communication over optic fiber cables, rather than magnetic recording.
