A and C can't work because it doesn't match the NLS date format, D works fine by implicit conversion , so it's BE

E says 'explicit' did you see any conversion function? A works, as MON is for the full month name and RR.. just google it.

C. invoice_date > '01-02-2019': This statement uses implicit conversion. The date string is implicitly converted to a DATE type using the default date format. D. qty_sold = '0554982': This statement requires explicit conversion. You need to explicitly convert the string to a NUMBER to compare it with the QTY_SOLD column.
