Detailed explanation-1: -Data Integration − In this step, multiple data sources are combined.
Detailed explanation-2: -Explanation: Unsupervised learning is a type of machine learning algorithm that is specifically designed to identify the abstracted patterns in unlabeled data.
Detailed explanation-3: -Answer: c. Explanation: Euclidean distance measure can be defined as the calculating distance between two points in either in-plane or three-dimensional space measures the length of the segments connecting two points. It can also define as the distance between two points as calculated using the Pythagoras theorem.
