To answer this question, we need to understand the concept of a "clique."
A clique is a collection of nodes in a graph, where every node is directly connected to every other node in the collection. In other words, in a clique, every pair of nodes is connected by an edge.
Let's go through each option to determine which one represents a collection of nodes:
Option A) AMP - AMP stands for Accelerated Mobile Pages. It is a web component framework developed by Google. However, it does not represent a collection of nodes in the context of a clique. Therefore, option A is incorrect.
Option B) PE - PE could refer to several things, such as Physical Education or Private Equity. However, neither of these options represents a collection of nodes in the context of a clique. Therefore, option B is incorrect.
Option C) NODE - NODE represents a collection of nodes in the context of a clique. In a graph, a clique is a collection of nodes where every node is directly connected to every other node. Therefore, option C is correct.
Option D) Vdisk - Vdisk does not represent a collection of nodes in the context of a clique. Therefore, option D is incorrect.
The correct answer is option C) NODE. This option is correct because a clique is indeed a collection of nodes in a graph.
