Solution

The answer is the second one: Use SOQL to query all of the records in the "Tasks" object and filter the results based on specific criteria.

Explanation for each option:

Use indexing to optimize the performance of the query.
- Indexing can improve query performance, but it is not a method to retrieve records. It is a technique to optimize the retrieval process.
Use SOQL to query all of the records in the "Tasks" object and filter the results based on specific criteria.
- This is the correct option. SOQL (Salesforce Object Query Language) is specifically designed to query records from Salesforce objects. You can use SOQL to retrieve specific records from the "Tasks" object by applying filters based on criteria such as Task Name, Due Date, and Priority.
Use the trigger.newMap collection to retrieve the necessary records.
- The trigger.newMap collection is used in the context of triggers to access new records that are being inserted or updated. It is not used for querying existing records from an object.
Use a scheduled batch job to process the records in batches.
- A scheduled batch job is useful for processing large volumes of records asynchronously, but it is not the most efficient way to retrieve specific records based on criteria. It is more suitable for bulk processing tasks.

Summary: To retrieve specific records from the "Tasks" object when it contains a large number of records, you should use SOQL to query all of the records in the "Tasks" object and filter the results based on specific criteria.
