Pipes are commonly used for communication between OS components and for exchanging messages between components in a large program.

Answer: D 
 Procedures can also be used for communication between OS components and exchanging messages between components in a large program. However, the question specifically mentions queuing requests to an OS service, which is not typically accomplished through procedure calls. Therefore, while procedures can be used for communication and message passing, pipes are the more relevant answer for this question.

Sockets are typically used for communication between separate processes or even separate devices on a network, so they are not as relevant for communication within an OS. Packets are a lower-level concept that refers to the format in which data is transmitted across a network, so they are not directly related to communication between OS components.
