In B-Rank standards, missing colors and mixed piles of colors are permitted.

• A. True
• B. False
• C. Not Specified
• D. Optional

Answer: (A)

In B-Rank standards, the priority is efficient processing and speed in handling daily operations, so some flexibility with color handling is allowed. Missing colors means not every color variant needs to be present for a given batch, and mixed piles of colors mean you can group different color variants together rather than sorting them into strict, separate piles. This flexibility helps keep workflows moving and reduces extra steps, which is important when throughput matters more than perfect color separation. If a specific color variant is truly essential, that requirement would typically be addressed in higher ranks or separate procedures, but within B-Rank the described flexibility is permitted, so the statement is true.
