The correct choice identifies carriers that focus on parcel, courier, and express services, which are vital components of logistics and distribution. These carriers specialize in the movement of smaller packages and documents over short to medium distances with a focus on speed and reliability.

Parcel carriers are designed for the delivery of small packages, typically weighing no more than 150 pounds, catering to individual and business needs. Courier services offer expedited delivery, often same-day or next-day, directly to recipients, ensuring quick turnaround times. Express services prioritize fast delivery, often utilizing a combination of ground and air transport to minimize transit times.

Other options don’t encompass the entire scope of parcel and express services. Standard post carriers generally focus on weightier or bulk items without the added urgency conveyed by express services. Air freight carriers specialize in larger shipments that require air transportation but do not specifically address the urgency and individual delivery aspect associated with parcel services. Intermodal carriers utilize multiple transport methods (like truck, rail, and water), but again, do not focus solely on the timely delivery characteristic of parcel and express services.

Thus, the selected option accurately captures the essence of carriers specifically associated with parcel, courier, and express services, highlighting their unique characteristics and services within the logistics sector.
