Final Answer :
B
Explanation :
According to the IREF shown, the pushbutton is connected to the input card and the output card through the contact of the PLC. When the pushbutton is momentarily actuated, the contact of the PLC closes for one scan, which latches the data in the input card, and then sends the data to the output card for one scan. Therefore, the data is latched in for one scan.
