Answer: Option B

Explanation:

The main advantage of a layered model is that it can allow application developers to
change aspects of a program in just one layer of the layer model’s specifications.

Advantages
of using the OSI layered model include, but are not limited to, the following:

It divides the
network communication process into smaller and simpler components, thus aiding compo-
nent development, design, and troubleshooting;

it allows multiple-vendor development
through standardization of network components;

it encourages industry standardization by
defining what functions occur at each layer of the model;

it allows various types of network
hardware and software to communicate;

and it prevents changes in one layer from affecting
other layers, so it does not hamper development.
