Answer:
e. Debit Petty Cash $50    Credit Cash  $ 50
Explanation:
The entry on October 01 is to reflect the increase in Petty Cash from $ 250 to $ 300. i.e the incremental effect is only $ 50. This is because for the regular replenishment that was done on September 30, the following entry would have been recorded:
Petty Cash - Debit  $ 232
Cash      - Credit  $ 232
The entry for recording the petty cash expenses would be as follows;
Office Supplies expense     debit   $ 73
Merchandise Inventory      debit   $ 137
Miscellaneous expenses     debit    $ 22
Petty Cash                credit   $ 232
