Final Answer :
B
Explanation :
When a field device contact connected to the input module closes, a logic 1 is recorded in the memory location of the contact with the same address. This is because the input module is designed to register the status of the field device contacts, and a closed contact is interpreted as a logic 1 input. The coil with the same address refers to the output module, which would be affected by the input status change but not directly related to the input module's memory location.
