A

Nearest-Neighbor Un-embedding

B

Linear Regression

C

Decision Trees

D

Support Vector Machines

Understanding the Answer

Let's break down why this is correct

The method looks at the distance between the new point and all known points. Other options are incorrect because Linear regression predicts a numeric value, not a class label; Decision trees split data on feature thresholds, not on distance.
