D Pub. 102, International Code of Signals
AI Explanation

The correct answer is A) Pub. 117, Radio Navigational Aids. Pub. 117, Radio Navigational Aids, contains information on Naval Control of Shipping (NCS) procedures in times of emergency or war. This publication provides guidance on the communication and coordination requirements for merchant vessels under NCS, which is a critical function of the U.S. Coast Guard during wartime or national emergencies. The other answer choices do not contain the specific information on NCS that is found in Pub. 117. The Light List, Sailing Directions, and International Code of Signals publications focus on different types of navigational and communication information, but do not cover the details of NCS operations.
