Final answer:
The 'manage customer accounts' process in a logical DFD for a B/AR/CR process would interact with the accounts receivable master data.
Step-by-step explanation:
In a logical DFD for a B/AR/CR process, the data store that would be expected to interact with a process called 'manage customer accounts' is the accounts receivable master data.
This data store will contain information about the customer accounts, such as account balances, payment history, and customer contact details. The process of 'manage customer accounts' will interact with this data store to perform various tasks related to managing and updating customer accounts.
On the other hand, the other data stores listed, such as the inventory master data, sales event data, and cash receipts event data, are not directly related to the management of customer accounts and would not be expected to interact with the 'manage customer accounts' process.
