A large company uses Salesforce across several departments. Each department has its own Salesforce Administrator. It was agreed that each Administrator would have their own sandbox in which to test changes.
Recently, users notice that fields that were recently added for one department suddenly disappear without warning. Also, Workflows that once sent emails and created tasks no longer do so. Which two statements are true regarding these issues and resolution? Choose 2 answers

• A.The administrators are deploying their own Change Sets over each other, thus replacing entire Page Layouts and Workflows in Production
• B.Page Layouts should never be deployed via Change Sets, as this causes Workflows and Field-level Security to be reset and fields to disappear.
• C.The administrators are deploying their own Change Sets, thus deleting each other's fields from the objects in production.
• D.A sandbox should be created to use as a unified testing environment instead of deploying Change Sets directly to production.

{
List<Account> accountList = new List<Account>();
for( Account anAccount : trigger.new )
{
Region__c theRegion = [
SELECT Id, Name, Region Manager__c
FROM Region__c
WHERE Name = :anAccount.Region_Name__c
];
anAccount.OwnerId = theRegion.Region_Manager__c;
