A. B. C. D.A.
The correct answer to this question is A. Trigger.newMap and Trigger.oldMap.
When a trigger is executed in Salesforce, it receives a list of records that are being modified. These records are represented as sObjects (Salesforce objects). In order to efficiently work with these records in a trigger, you can convert the list of sObjects to a map of sObjects using the Trigger.newMap and Trigger.oldMap methods.
Trigger.newMap is a map that contains the new versions of the sObjects being modified, where the keys are the record IDs. This allows you to easily access and work with the new versions of the records in the trigger.
Trigger.oldMap is a map that contains the old versions of the sObjects being modified, where the keys are the record IDs. This allows you to easily access and compare the old versions of the records to the new versions, which can be useful for detecting changes and implementing custom logic in the trigger.
The IDI-to-sObject maps mentioned in the question refer to the relationship between the IDs of the records being modified and the sObjects themselves. By using Trigger.newMap and Trigger.oldMap, you can create this mapping and efficiently work with the records in the trigger.
Option B, internal and external, and option D, queues and time triggers, are not related to the mapping of IDs to sObjects and are not valid answers to this question.
Option C, Trigger.new, is a valid method for accessing the new versions of the sObjects being modified, but it does not create the map of ID-to-sObject relationships that is necessary for the question. Therefore, option A is the correct answer.
