Which organization operates and maintains the ships providing logistic support?

The correct answer is C, as the Military Sealift Command (MSC) is the organization responsible for operating and maintaining the ships that provide logistic support to the U.S. Navy and other military branches. MSC plays a critical role in ensuring that naval vessels have the necessary supplies, fuel, and equipment to sustain operations at sea. It manages a diverse fleet that includes supply ships, fuelers, and other vessels that transport goods and personnel, ensuring continuous support to Navy operations globally.

To understand the context further, NAVSUP (Naval Supply Systems Command) focuses on supply chain management and logistics support, but it does not operate the ships themselves. CLO (Contract Logistics Support) refers to administrative and contractual aspects of logistics and does not directly relate to the operation of ships. DBIDS (Defense Biometric Identification System) pertains to security and access management, which is unrelated to logistical support or shipping operations. The role of MSC is specifically integral to maritime logistics, making it the correct choice in this scenario.
