How does data encapsulation work with the protocol stack?

A.
Each layer in the OSI model multiplexes other packets to the data as it is passed down the protocol stack.

B.
Each layer in the OSI model adds its own information to the data as it is passed down the protocol stack.

C.
The packet is encapsulated and grows as it hops from router to router.

D.
The packet is encapsulated and grows when it is passed up the protocol stack.

Explanation:
Data encapsulation means that a piece of data is put inside another
type of data. This usually means that individual protocols apply their own
instruction set in the form of headers and trailers. As a data package goes down the
OSI, or protocol stack, of a system, each protocol that is involved adds its own
instructions. This process is reversed at the destination.
