Mauritz Question, Bank Reconciliation, what counts as an outstanding lodgement?

Hi Mr Moffatt! Please help me with this one Mauritz Co is preparing a bank reconciliation. The bank balance in the general ledger is $540 credit. There are two items that have not yet been dealt with. 1 A cheque for $620 was sent to a supplier but is not yet showing on the bank statement. 2 A bank charge of $28 was charged by the bank, but was not recorded by Mauritz Co. What is the closing balance on Mauritz Co’s bank statement? A $1,132 overdrawn B $1,188 overdrawn C $52 cash at bank D $108 cash at bank ans is C, I know the answer to this is C but I do not understand why the check issued to a supplier counts as an outstanding lodgement. Doesn't that suggest the money in fact is paid to our bank instead of the other way around? I thought we can use a check to pay suppliers?
