Final answer:
Salesforce triggers can execute custom Apex code due to certain record operations, and the context variable 'isInsert' returns true if the trigger was fired by an insert operation.
Step-by-step explanation:
The statement in question is related to Salesforce, a customer relationship management (CRM) platform. One of the features offered by Salesforce is 'triggers', which allow developers to run custom Apex code in response to certain events on Salesforce records, such as insertions, updates, deletions, etc. When a trigger is fired because of an insert operation, whether the operation is performed through the Salesforce user interface, an Apex script, or an external API, there is a context variable called isInsert that returns true. Therefore, the correct answer to the statement is indeed 1) True.
