Salesforce imposes specific data-integrity requirements before individual-model Account and Contact records can be converted into Person Accounts. First, every individual account being transformed must have only one direct Account Contact Relationship and one associated Contact. This is necessary because the resulting Person Account combines the Account and individual Contact information into a single person-oriented record.

The account must also not be the parent of another Account. Salesforce requires the Account ' s Parent Account field to be blank and explicitly states that an account being converted cannot be the parent account of any other Account records.

The conversion should also be tested comprehensively in a sandbox. Salesforce describes the conversion as irreversible and instructs organizations to create a sandbox first so they can evaluate the effects of Person Accounts on technical architecture, integrations, automation, and customizations.

Additional documented requirements include matching Account and Contact owners, matching currency values where applicable, ensuring that the Contact ' s Reports To field is blank, and ensuring that no other contacts report to that Contact. There is no requirement for the Account Phone field to be blank, nor does Salesforce require linked Opportunities to be reassigned to the Account owner as a conversion prerequisite. Therefore, A, B, and E are the mandatory preparations represented in the answer choices.
