Explanation:

1. Delimers are specifically formulated to break - down and remove mineral deposits such as lime scale.
2. Abrasive cleaners have rough particles that can physically scrub away baked - on food or tough soil.
3. The correct contact time for a sanitizer is the manufacturer's recommended time as it varies based on the product's formulation.
4. Scrubbing for 20 seconds is not a standard step in the general 5 - step cleaning and sanitizing process which typically includes washing, rinsing, sanitizing, and air - drying.
5. In a 3 - compartment sink, the second sink is usually for rinsing after washing in the first sink and before sanitizing in the third sink. But among the given options, no correct answer is provided as the second sink is the rinsing one and not listed. However, if we assume the options are limited, the most logical would be to say none of the above as the first sink is for washing.

Answer:

1. c) Delimer
2. d) Abrasive cleaner
3. c) The manufacturer's recommended time
4. b) Scrub for 20 seconds
5. None of the above (as the correct rinsing sink is not among the options)
