Answer:
A. Social network analysis (SNA).
Step-by-step explanation:
This is explained to be a process of quantitative and qualitative analysis of a social network. It measures and maps the flow of relationships and relationship changes between knowledge possessing entities. Simple and complex entities include websites, computers, animals, humans, groups, organizations and nations.
The SNA structure is made up of node entities, such as humans, and ties, such as relationships. The advent of modern thought and computing facilitated a gradual evolution of the social networking concept in the form of highly complex, graphical based networks with many types of nodes and ties. These networks are the key to procedures and initiatives involving problem solving, administration and operations.
