The Method A procedure allows multiple samples to be soaked and suspended simultaneously.

• A. No, only one at a time
• B. Only two samples
• C. Not specified
• D. Yes, multiple samples

Answer: (D)

Batch processing is the idea here: when a procedure allows soaking and suspending multiple samples at once, you can treat several samples in the same step, using the same solvent, duration, and agitation for all of them. This makes the process more efficient because you’re handling fewer separate operations, and it also helps ensure consistency across samples since everyone gets the same exposure time and conditions. To do this properly, label each sample clearly, use containers that keep them separate but allow full immersion, and keep the same temperature and mixing conditions for the entire batch so no sample ends up under- or over-exposed. The other options imply limits or uncertainty about capacity, which isn’t the case here—the procedure supports multiple samples.
