Answer:
The correct option is None of the above options.
Explanation:
When closing entry is posted for the Income summary, then the income summary account is debited and the retained earnings account is credited when it is a company. So, in this case, it is a company, then the journal entry would be:
Income Summary A/c................Dr $12,000
To Retained Earnings A/c..............Cr $12,000
Earlier the income summary account has a credit balance, in order to close the account, then it will be debited with the same amount.
Hence, None of the given options is correct.
