💡 Detailed Explanation
The idiom '途方に暮れる' (tohō ni kureru) means 'to be at a loss' or 'to not know what to do'. '途方' itself means 'way' or 'direction', but it is almost exclusively used in this expression. The other options, '道端' (michibata - roadside), '迷路' (meiro - maze), and '行方' (yukue - whereabouts), do not fit to form this idiom.
