The type of network that typically includes people in the same department at the same level (peers) and people in different departments at the same level is:

A) external
B) vertical
C) lateral
D) exponential

Lateral networks refer to connections between people at the same level in different departments or areas of the organization, as well as connections between peers in the same department. This type of network facilitates collaboration and information sharing among colleagues who may not interact regularly in the course of their work. External and vertical networks refer to different types of connections between different levels of the organization and with outside partners or stakeholders, while exponential networks imply a rapidly growing or expanding network.
