The correct option is 3 then 4 then 2 then 1 then 5.

This sequence corresponds to the normal Azure Cognitive Search enrichment pipeline where the indexer retrieves documents from the data source first and then the content is extracted and parsed. After parsing the skillset runs and your custom skill performs language detection and sentiment scoring to produce enriched fields. The enrichment outputs are merged back into the document and then the enriched documents are written into the index for querying.

5 then 3 then 2 then 4 then 1 is incorrect because it places the final indexing step at the start. Indexing cannot occur before document extraction and enrichment have produced the fields that need to be indexed.

1 then 4 then 2 then 5 then 3 is incorrect because the steps are out of order and would represent running later pipeline actions before the necessary parsing and enrichment stages have completed.

4 then 2 then 3 then 1 then 5 is incorrect because it implies the skill execution or other intermediate steps happen before the document has been properly extracted and prepared for enrichment, so the enrichment would not have the correct inputs.
