Final Answer :
C
Explanation :
DN (Down) member of the timer structure indicates that accumulated value is equal to the preset value. Once DN becomes true, the output will switch its state. PRE (Preset) member defines the preset value for the timer. EN (Enable) member enables the timer, and TT (Timer Timing) member stores the current accumulated value of the timer.
