Which is not one of the eight levels of saturation alleviation?

• A. FRND 1
• B. FRND 2
• C. FRND 5
• D. FRND 3

Answer: (C)

Saturation alleviation levels are a fixed, predefined set identified by specific FRND numbers. Each FRND label corresponds to a defined relief configuration, and the eight official levels include certain FRND identifiers. Among the options, FRND 5 does not appear in that official list, while FRND 1, FRND 2, and FRND 3 are part of the defined levels. That makes FRND 5 the one that isn’t a valid level in this scheme. When studying, focus on memorizing which FRND numbers are actually defined for the eight saturation relief levels, since any label outside that set isn’t a recognized level.
