Final answer:
In the context of general ledger control accounts, 'Sundry Debtors' is most likely to be the correct answer as it is used to summarize transactions of individual debtors recorded in a subsidiary ledger.
Step-by-step explanation:
The general ledger control account most likely to be found in the options provided is b. Sundry Debtors. Control accounts are used in accounting to summarize the details of transactions that are individually contained in subsidiary ledgers. A sundry debtor account is used to record the total amounts owed by all individual debtors, which are detailed in the sales ledger, another type of subsidiary ledger. Owners Equity, although it is a general ledger account, it's not typically a control account. Prepaid Rent and Petty Cash are both examples of general ledger accounts that would typically contain detailed entries themselves rather than summarizing subsidiary ledgers.
