Sum the planned expenses
\[
\text{Total Expenses} = 85,210 + 725,726 + 203,396 + 322,800
\]
\[
\text{Total Expenses} = 1,337,132 \text{ won}
\]
Calculate the remaining budget
\[
\text{Remaining Budget} = \text{Total Budget} - \text{Total Expenses}
\]
\[
\text{Remaining Budget} = 2,192,896 - 1,337,132
\]
\[
\text{Remaining Budget} = 855,764 \text{ won}
\]
Match with the correct option
