Question 2673 Deck General

The correct answer is D) a registered professional engineer. According to the Coast Guard's fire protection regulations, a registered professional engineer must certify the fire detection system on a towing vessel to ensure it complies with the regulations. This requirement is in place to ensure the system is designed and installed properly by a qualified, licensed professional. The other options (A, B, C) are not authorized to provide this certification, as they do not have the necessary professional qualifications and licensing required by the regulations.
