Final answer:
Palm OS memory is organized into chunks known as records, where each database contains records for managing and organizing data.
Step-by-step explanation:
In Palm OS, memory is organized into chunks known as records (option b). Data in Palm OS is stored in databases, which are collections of records. Each database can be viewed as a file containing records, where each record is a piece of information. For instance, a contacts database would have an individual record for each contact entry. These records can then be categorized or sorted as per the application's logic, offering a flexible way to manage memory and organize data.
