Matching ML tasks to the correct algorithms

In the following table, the Task column lists a few tasks related to machine learning. The Algorithm column lists a few algorithms. Each entry “t” from the Task column is to be matched with an appropriate entry “a” from the Algorithm column such that the task “t” can be solved using the algorithm “a”. Denote such a match as t:a

| Task | Algorithm | |—|—| | T1 – Clustering | A1 – Markov Chain Monte Carlo | | T2 – Classification | A2 – K-Medoid | | T3 – Sampling | A3 – Linear Discriminant Analysis | | T4 – Feature Extraction | A4 – Naive Bayes |

Which of the following options is/are the correct matching(s)?
