Step-by-step explanation:
The student has asked a question about the representation of project activities in a network diagram. An Activity on Node (AoN) network, referred to in the question, shows the activities on the nodes and is also known as precedence notation.
This is contrasted with an Activity on Arrow (AoA) network, where the activities are represented on the arrows and is also known as arrow notation. Here, the correct answer to the given question is that an AoN network shows the activities on the nodes and is known as precedence notation, thereby making option C correct.
The answer is option ⇒C
