The correct answer is A. Between 1945 and 1975 the U.S. government secretly monitored telegram traffic entering and leaving the United States, as well as other communications. The name of this project was Operation Shamrock.

Explanation:

Project Shamrock was a spy program of the intelligence agency NSA. It started in 1945 and was used to record and evaluate all telegrams that crossed the borders of the USA in both directions.  

The basis of the program was the cooperation of private telegraph companies such as Western Union. They collected copies of the telegrams, which were stored first on punch cards and then on magnetic tapes, and made them regularly available to the NSA.
