Which of the following is true?

A. Error of casting affects personal accounts
B. Omission of a transaction from a subsidiary record affects only one account
C. Error of carry forward affects two accounts

Statement C. is false. Errors of principle involve incorrect allocation of an item between capital and revenue. Hence statement D. is true.
