Final answer:
Electronic ROEs are accurately submitted to Service Canada through the online ROE Web platform. The other methods like fax, carrier pigeon, and Morse code are either outdated or not applicable.
Step-by-step explanation:
The question asks about the methods of submitting Electronic Records of Employment (ROEs) to Service Canada. ROEs are a crucial document for Canadian employees as they provide a record of their work history when they leave an employer. The accurate method for submitting electronic ROEs is online through the ROE Web. This secure platform allows employers to create, submit, and manage ROEs electronically. While the other options, such as fax transmission, might seem plausible, they are either outdated or humorous suggestions. Carrier pigeon delivery and Morse code telegrams are not viable methods for submitting ROEs in today's digital world.
