Shunts and siding are components found in which mode of transportation?

Shunts and siding are terms specifically associated with railway transportation. A shunt refers to a method of diverting a train from one track to another or to maneuver trains within a yard for loading and unloading operations. Siding refers to a secondary track that runs parallel to the main track and is used for allowing trains to pass one another or to park cars when not in use. These components are integral to the operation and management of rail systems, facilitating the safe and efficient movement of trains and freight.

In contrast, road transport does not utilize shunts or sidings, as street and highway systems function differently from railways. Aviation primarily deals with air traffic and airfield operations, which do not involve rail components. Maritime transportation features ports and docks, and while it may include moving cargo using rail systems once it reaches land, shunts and siding are not part of that operation. Thus, the correct association of these terms is with railways.
