1. A, C. Options B and D are valid regularization terms, but they will not penalize small weights as much as the L1 penalty.
2. B. Option C is also unsupervised, but LDA is not used on tabular datasets but rather on textual data. Options A and D are supervised learning algorithms.

4. C. Options A and B are complex solutions requiring a lot of custom development. Rekognition does not detect PII, so only option C is correct.
5. C. SageMaker Processing and Batch Transform jobs are not ...
