Answer : B, C

Option B:Custom events in LWC allow data to be passed using thedetailproperty of theCustomEventobject. This is the recommended way to pass data in a custom event.

Question 4

A developer wants to get access to the standard price book in the org while writing a test class that covers an OpportunityLineltem trigger.

Which method allows access to the price book?

AUse Test .getStandardPricebookid() to get the standard price book ID.

BUse @isTest [SeeAllData=true| and delete the existing standard price book.

CUse @Testvisible to allow the test method to see the standard price book.

DUse Test. loadData () and a static resource to load a standard price book.

Answer : A

When writing test classes, accessing the Standard Price Book is essential for creatingOpportunityLineItemrecords.

The methodTest.getStandardPricebookId()is specifically designed to retrieve the Standard Price Book ID in a test class context. This ensures you can work with the price book without requiring@isTest(SeeAllData=true).

Why not other options?

B:@isTest(SeeAllData=true)is not recommended because it violates Salesforce best practices by accessing actual org data.

C:@TestVisibleis used for visibility between classes but does not relate to retrieving Standard Price Book.

D:Test.loadData()loads test data from static resources but is unnecessary for accessing the Standard Price Book.
