Option C is correct because Product Batch Item is the Salesforce Life Sciences Cloud record that connects a production batch to a specific product inventory location or user inventory context. Salesforce Help describes creating Product Batch Items for sample inventory and states that a product batch item establishes the relationship between the Product, Life Science Marketable Product, Production Batch, Product Batch Item, Location, and User. This directly matches the scenario: Cumulus Pharma needs to allocate samples from a specific production batch to a field sales rep’s inventory and track remaining quantity at the batch level.

The ProductBatchItem object also includes the RemainingQuantity field, which supports the requirement to track remaining quantity by batch. Salesforce’s Life Sciences Cloud Developer Guide documents ProductBatchItem and identifies RemainingQuantity as a field on the object.

Option A is incorrect because simply assigning a Production Batch to the Life Sciences Marketable Product does not allocate batch-specific stock to a rep’s inventory. Visit submissions can update inventory, but the batch allocation must already be represented correctly. Option B is also incorrect because updating Quantity on Hand on Product Item only changes general product inventory at a location. It does not establish the production-batch relationship needed for batch-level tracking. Therefore, the consultant should create a Product Batch Item, associate it to the rep’s Product Item, mark it Active, and enter the Remaining Quantity.
